Songwriting glossary: 70 terms and definitions, with audio

This songwriting glossary defines 70 terms in plain English, grouped by what they describe: song structure, lyrics, melody, harmony, rhythm, recording, and credits and rights, each group A to Z. Every entry gives a short definition, an example and, where one exists, a link to the in-depth guide or free tool. Eight entries include audio you can play in the browser: short teaching sketches synthesized on the spot, not studio recordings.

If you learn only four words, learn these: the verse tells the story and changes its words, the chorus repeats the main idea, the hook is the part nobody forgets, and the bridge is the one-time contrast before the last chorus.

Often confused	The difference
Chorus and hook	The chorus is a section; the hook is the most memorable element, often inside it
Chorus and refrain	A chorus is a whole section; a refrain is one line that returns
Melody and topline	Any tune vs. a vocal melody and lyric written over an existing track
Mixing and mastering	Balancing one song’s tracks vs. finishing the mixes as a set
Composition and master	The song itself vs. one recording of it
ISWC and ISRC	The code for the composition vs. the code for a recording

Song structure terms

AABA form

Three verses (A) that end on the title, plus one contrasting bridge (B), with no separate chorus. Many standards use it in 32 bars, four sections of eight. Example: every A ends “…and I’m still waiting.” The song structure planner offers AABA as a starting form.

Bridge

A section, usually heard once after the second chorus, with new chords, melody or angle, so the last chorus feels earned; in the UK, the middle eight. Guide: how to write a song bridge.

What to listen for: the chorus runs from 0:02 to 0:12; at 0:12 the bridge drops to A♭ with softer drums and longer chords, and at 0:21 the chorus sounds brighter by contrast.

Chorus

The section that repeats with the same words and melody and carries the main idea, usually with the title. It tends to sit higher than the verse. Example: four lines that open and close on “Leave the light on.” Guide: how to write a chorus.

Intro

The opening before the first vocal, often two to eight bars of the chorus chords or the main riff. Example: four bars of the guitar riff, then verse one. Guide: song structure with examples.

Outro

The ending after the last chorus: a fade, the intro riff returning, or a tag, one line repeated to close. Example: the last chorus line sung three times over one held chord.

Post-chorus

A short section right after the chorus that repeats a chant, a vocal riff or an instrumental hook. Example: “oh-oh, leave the light on” twice over the chorus chords.

Pre-chorus

A short section between verse and chorus that builds tension with shorter lines, a rising melody and a chord that waits. Guide: how to write a pre-chorus.

What to listen for: a verse with no drums (0:02–0:12), arpeggios from 0:12, the G held for two bars from about 0:17, and the chorus resolving to C at 0:21.

Refrain

A line that returns at the same spot in every verse, usually the title, rather than a whole section. Many people use it as a synonym for chorus. Example: each verse of an AABA song ending “…and I’m still waiting.”

Verse

The section that moves the story forward: same melody, new words each time, usually lower and wordier than the chorus. Example: verse one shows the empty kitchen; verse two jumps to the morning after. Guide: how to write a verse.

Verse-chorus form

The most common pop form: verses alternate with a repeated chorus, often adding a pre-chorus and a bridge. Example: 72 bars of 4/4 at 96 BPM last exactly three minutes. Tool: song structure planner.

Lyric terms

Internal rhyme

A rhyme inside the line, not only at the end; a staple of rap. Example: “Late at the gate, I wait for the train.” Guide: types of rhyme in songs.

Multisyllabic rhyme

A rhyme that matches two or more syllables in a row, across several words. Example: “hold it together” and “cold in the weather.” Guide: how to write a rap song.

Perfect rhyme

Two words whose last stressed vowel and everything after it sound the same: night and light, falling and calling. Satisfying, but predictable in every line. Guide: types of rhyme in songs.

Prosody

The fit between words and music: stressed syllables on strong beats and long notes, and a melody shaped like the meaning. Example: “to-MOR-row” sung as “TO-mor-row” is bad prosody. Guide: song syllables and stress.

Rhyme scheme

The pattern of rhymes in a section, written with letters: AABB, ABAB or ABCB, where only lines two and four rhyme. Example: ABCB leaves lines one and three free for detail. Guide: types of rhyme in songs.

Show, don’t tell

Writing a concrete image or action instead of naming the feeling. Example: not “I’m so lonely” but “Two cups on the counter, one still clean.” Guide: how to write a verse.

Slant rhyme

A near rhyme, also called half rhyme: the vowels match, or the final consonants do, but not both. It sounds conversational. Example: home and alone, heart and hard.

Stressed syllable

The syllable a word leans on when spoken: to-MOR-row, HAP-py, a-GAIN. It should land on a strong beat or a longer note. Example: the long note of “again” goes on “-gain”.

Syllable count

The number of syllables per line. When two verses match line by line, they can share one melody. Example: “Two cups on the counter” has six. Tool: lyric syllable counter.

Title

The song’s name, usually the phrase the chorus repeats most, placed first or last in it. Example: “Leave the Light On” opens and closes its chorus. Guide: song title ideas.

Melody terms

Hook

The part of a song you cannot stop humming: a melodic phrase, a line, a riff or a sound, often the title on a short repeated tune. Guide: how to write a hook.

What to listen for: the same two-bar phrase of eight notes returns at about 0:02, 0:07, 0:12 and 0:17. By the third time you can hum it.

Leap

A jump between notes that are not neighbors in the scale, such as E up to C. Leaps give lift; a good melody then steps back the other way. Guide: how to write a melody.

What to listen for: the line jumps E–G–C to a high C at 0:04, steps down at 0:05, then leaps to a high D at 0:09.

Melodic contour

The shape of a melody drawn as a line: rising, falling, arch or flat. Example: a verse moving between C and G, a chorus peaking on high C. Guide: how to write a melody.

Melody

The sequence of pitches and rhythms the voice sings: the tune you would whistle. Example: sing a line on three notes, then add a fourth for the key word, over the practice melody. Guide: how to put music to lyrics.

Motif

A short musical idea, a few notes or a rhythm, that the song repeats and varies. Example: a one-bar figure, the same figure a step higher, then an answer.

Phrase

A musical sentence sung in one breath, often two or four bars, usually one lyric line. Example: four two-bar phrases make an eight-bar verse. Guide: how to put music to lyrics.

Riff

A short instrumental phrase repeated through a section, often on guitar or synth. When it is the most memorable part, the riff is the hook.

What to listen for: one bar of riff repeats from 0:02 to the end at 0:21. The notes never change, the chords do: over F, at 0:04, the riff sounds softer.

Stepwise motion

Movement to neighboring scale notes, such as C–D–E. Easy to sing and ideal for verses, though a whole song of it feels flat. Example: a verse line walking E–F–G–F–E.

Topline

The vocal melody and lyric written over an existing track or beat, by a topliner; the term comes from pop production. Example: a producer sends a 90 BPM loop and you write the chorus on top. Guide: what is a topline.

Vocal range

The span from the lowest to the highest note you sing comfortably; the key should keep the melody inside it. Example: top note E4, chorus peak G4: lower the key three semitones. Tool: what key should I sing in.

Harmony and chord terms

Borrowed chord

A chord taken from the parallel key, usually minor, for a darker color; also called modal interchange. Example: C–F–Fm–C, in the chord player. Guide: sad chord progressions.

Cadence

The chord move that ends a phrase and sets how final it sounds: V to I closes, stopping on V leaves it open. Example: G to C ends the chorus. Guide: chord progressions for songwriting.

Capo

A clamp across the guitar neck that raises every string one semitone per fret, so easy chord shapes sound in a higher key. Example: G shapes with a capo on fret 2 sound in A. The chord sheet maker suggests a capo position, and what key should I sing in gives one for your range. Guide: capo chart.

Chord chart

A sheet with the lyric and each chord name above the syllable where it changes; a lead sheet also writes the melody. Example: “[C]Leave the [G]light on.” Tool: chord sheet maker. Guide: lyric and chord sheet.

Chord progression

A sequence of chords that repeats under a section; four chords can carry a whole song. Guide: chord progressions for songwriting.

What to listen for: C, G, Am and F change every 2.5 seconds from 0:02, and the loop restarts at 0:12. Load it in the chord player and try another key.

Key

The home note and scale of a song, such as C major or A minor; the home chord, the tonic, is where the music rests. Example: a song in G usually starts and ends on G and uses G, C, D and Em.

Key change

Moving the song to a new key, also called modulation, often one or two semitones up for the last chorus. Example: the final chorus jumps from C to D.

Major and minor

The two main colors of a key: major sounds brighter, minor darker, mostly because of the third note (E in C major, E♭ in C minor). A minor is the relative minor of C major: same notes. Guide: sad chord progressions.

What to listen for: after the count-in (0:00–0:03), chords change at 0:03, 0:06, 0:09 and 0:12. At 0:12 the melody rises D–F–B♭ and stops one step short of home.

Nashville number system

Chords written as scale numbers, so a band can read one chart in any key. Example: 1–5–6m–4 is C–G–Am–F in C and A–E–F♯m–D in A.

Roman numerals

Chords named by scale degree: uppercase for major (I, IV, V), lowercase for minor (ii, iii, vi). Example: vi is Am in C and Em in G. Tool: chord progression player.

Transpose

To move every note and chord by the same interval. Example: C–G–Am–F up two semitones is D–A–Bm–G. Tool: chord sheet maker.

Rhythm and tempo terms

Bar

A group of beats, also called a measure: four per bar in 4/4. Sections are counted in bars; in rap, a bar is also one line. Guide: how to write lyrics to a beat.

Beat

The steady pulse you tap your foot to. In hip-hop and pop, “a beat” also means the instrumental. Example: at 90 BPM, one beat every 0.67 seconds.

BPM

Beats per minute, the measure of tempo: 60 BPM is one beat per second. Example: ballads often sit between 60 and 80 BPM. Tool: tap tempo metronome. Guide: what is BPM in music.

Click track

A metronome in your headphones while recording; the count-in is the bar of clicks before you start. Example: four clicks, then the verse. Tool: tap tempo metronome.

Flow

How a rapper or singer places syllables against the beat: rhythm, speed, pauses and stress. Example: one line in straight eighths, then in triplets. Guide: how to write a rap song.

Half-time

A feel with the snare on beat 3 instead of 2 and 4, so the song feels half as fast. Example: trap at 140 BPM feels like 70. Guide: what is BPM in music.

Pickup

Notes or syllables before the first strong beat of a phrase, also called an anacrusis. Example: in “and I LEFT the door open”, “LEFT” lands on beat 1. Guide: song syllables and stress.

Syncopation

Accents placed between the beats, so the rhythm pushes forward. Example: singing “open” just before beat 3 instead of on it.

Time signature

Two numbers: beats per bar and the note value that gets the beat. 4/4 for most pop, 3/4 for a waltz, 6/8 for two groups of three. Example: count “1-2-3, 1-2-3” for 3/4.

Triplet

Three equal notes in the space of two; a triplet flow puts three syllables on each beat. Guide: how to write a rap song.

What to listen for: from about 0:02 to 0:09, four bars with three syllables on each of beats 1, 2 and 3; beat 4 stays empty.

Recording and production terms

DAW

Digital audio workstation: software to record, edit and mix, such as GarageBand, Logic Pro or Ableton Live. Example: guitar and vocal on separate tracks. Guide: how to make a demo in GarageBand.

Demo

A rough recording that shows how the song goes, from a voice memo with guitar to a full home production. Example: voice and piano on a phone, one take. Guide: what is a demo in music.

Loop

A few bars of audio that repeat seamlessly; many songs are written over one. Example: four bars of Am–F–C–G at 92 BPM. Guide: how to write lyrics to a beat.

Mastering

The last step after mixing: loudness, tone and consistency, so the tracks sound right anywhere and together. Example: bringing the five songs of an EP to a similar level.

Mixing

Balancing the recorded tracks with levels, panning, EQ, compression and effects. Example: pulling the guitar down so the vocal sits on top. Guide: how to record a demo at home.

Scratch vocal

A quick guide vocal that holds the melody and lyric while other parts are built, replaced later. Example: singing quietly over the demo just to keep the timing. Guide: how to record vocals at home.

Stems

Groups of tracks exported as separate audio files, such as drums, bass and vocals, all starting at the same point. Example: four stems of equal length for a producer. Guide: how to share unreleased music.

Take

One recorded attempt; you keep the best or combine the best parts. Example: take three of the chorus has the cleanest high note. Guide: how to record demos with your phone.

Credits, business and rights terms

This section describes how things generally work; it is not legal advice.

Co-writing

Writing a song with one or more people, who then share its authorship. Example: one brings the title and chords, the other the melody, and both agree the split. Guide: how to run a co-writing session.

Composition

The song as a work: melody, harmony and lyric, apart from any recording; also called the musical work. Example: a band covers your song; the recording is theirs, the composition yours. Guide: songwriting royalties explained.

Copyright

The legal right over a creative work. In the US it exists once the work is fixed in a tangible form; registration is voluntary, but needed to sue over a US work. Example: a voice memo fixes the song. Guide: how to copyright and register a song.

ISRC

International Standard Recording Code: 12 characters that identify one recording or music video, not the song. Example: the acoustic and studio versions carry two ISRCs. Guide: music distribution.

ISWC

International Standard Musical Work Code: identifies the composition, as T plus nine digits and a check digit. Example: your song and every cover share one ISWC. Guide: songwriting royalties explained.

Master recording

The finished recording, owned by whoever made or paid for it, often the artist or a label, with royalties of its own. Example: you own the song; the label owns the master it financed.

Mechanical royalties

Money for reproducing a composition: physical copies, downloads and on-demand streams. In the US, The MLC collects them from streaming and download services. Example: every stream adds a tiny mechanical share. Guide: songwriting royalties explained.

Performance royalties

Money paid when a composition is performed in public, on radio, TV, stages or streams, split into a writer’s share and a publisher’s share. Example: a café playing your song pays through its license.

PRO

Performing rights organization, the society that licenses public performance and pays writers and publishers: ASCAP, BMI or SESAC in the US, PRS for Music in the UK, SOCAN in Canada. Guide: songwriting royalties explained.

Split sheet

A short document, signed by every co-writer, with each person’s share of the song. Example: three writers sign 40/30/30 on the day. Tool: split sheet template. Guide: what is a split sheet.

Sync license

Permission to pair a composition with picture: film, TV, ads or games; the recording needs its own master-use license. Example: a series uses 30 seconds of your chorus.

Where Zoundroom fits: the vocabulary inside one song project

In Zoundroom each song is a project that keeps its recordings, lyric, notes and files together. Write the lyric in a note with the sections labeled and the key, BPM and capo on the first line, then record the topline inside that note: the audio lands at the cursor, under its section. Keep the signed split sheet in the same project. Zoundroom is not a DAW: mix elsewhere, then import the result. To use these terms on a real song, try the free songwriting course.

Frequently asked questions

What are the parts of a song called?

Intro, verse, pre-chorus, chorus, post-chorus, bridge and outro. Most pop uses verse–chorus form; many older standards use AABA, with the title at the end of each verse instead of a chorus.

Is the hook the same as the chorus?

No. The chorus is a section; the hook is the most memorable element, and it can sit inside the chorus (the title line), in the intro (a riff) or in a post-chorus chant.

What is the difference between the composition and the master?

The composition is the song, owned by its writers and publishers; the master is one recording of it, owned by whoever made it. Each has its own code (ISWC and ISRC) and its own royalties.
