AABB rhymes lines 1 and 2, then 3 and 4. ABAB connects 1 with 3 and 2 with 4. ABCB connects 2 with 4 while giving 1 and 3 different endings. To choose, keep one scene in view, try all three arrangements and compare meaning, word order and delivery. The rhyme planner lets you assign these labels; it does not hear or create rhymes. Pick the version that serves your verse, not the pattern with the most matching endings.
Keep the scene fixed. Notice what else moves.
Our original scene starts with a planned film night in a community hall. The screen stays blank, someone sings and the chairs become a circle. That change from watching to joining in is the thought we want to keep. Save your starting version before experimenting. If your own scene changes so much that it tells a different story, you are comparing two songs as well as two rhyme schemes.
Pat Pattison's Berklee lesson treats phrase count, phrase length, rhythm and rhyme arrangement as separate choices that work together. This exercise focuses on the last choice without pretending the others stay untouched. Our AABB and ABAB versions use exactly the same four lines in a different order. The ABCB version rewrites two lines, so its extra detail and different phrasing are part of the tradeoff.
Letters name end-sound families, not particular words or musical notes. In our first two versions, wall/hall is A and sing/ring is B. Say those endings in your intended voice before assigning labels. For this exercise, use one complete lyric phrase per row and keep those phrase boundaries consistent; changing the line breaks can change the written scheme too.
AABB: let each pair finish a small thought.
The first version below ends wall, hall, sing, ring. The first two lines pair preparation with the neighbours' arrival. The next two pair the failed screening with a new arrangement of the room. Each sound returns in the very next line. That gives us two local connections to try in performance; it does not make AABB cheerful, childish or simple by definition.
For this scene, the useful gain is the sequence: room prepared, people arrive, screening fails, people adapt. The possible cost is that the verse falls into two equally neat pairs when we might want the interruption to feel less tidy. Test that against the melody before rewriting. A clear chronological version is worth keeping even if another scheme looks more intricate.
At the writing desk
A film night becomes a circle of chairs
First thought
We pin a bedsheet to the wall
The neighbours squeeze into the hall
The screen stays blank; you start to sing
We pull the chairs into a ring
Another way in
We pin a bedsheet to the wall
The screen stays blank; you start to sing
The neighbours squeeze into the hall
We pull the chairs into a ring
- First thought: AABB uses wall/hall, then sing/ring. Each pair connects adjacent lines.
- Another way in: ABAB keeps every word and swaps only the middle lines. Wall/hall and sing/ring now connect alternating lines.
- The reorder also moves the neighbours' arrival until after the singing begins. Sound arrangement and story sequence both change; ABAB is an alternative, not a correction.
- The ABCB version below keeps ABAB's second and fourth lines, replacing wall and hall with doorway and fiddle. It changes the detail and phrasing as well as the rhyme pattern.
Original teaching lyrics. Compare intended end sounds in your own voice; no melody, performed test or audience response is supplied.
ABAB: hear an ending return across another line.
The second version in the comparison swaps the middle two lines. Its endings are wall, sing, hall, ring. Wall now waits until line 3 for hall; sing waits until line 4 for ring. The words are unchanged, but the audience now enters after the singing begins. That can suggest people being drawn into an improvised event. It also loses the first version's clear sense that everyone was already there for the failed film.
Neither sequence is an error. Choose the one you intend. If you need alternating rhymes and the original chronology, rewrite a whole phrase instead of moving lines blindly. A new ending must still belong to the action. Read without the letters once: if the only reason for an arrival, object or awkward sentence is to complete ABAB, revise the thought before hunting for another rhyme.
ABCB: spend the two open endings on useful detail.
Now keep lines 2 and 4 of ABAB and rewrite lines 1 and 3: “We pin a bedsheet by the doorway / The screen stays blank; you start to sing / A neighbour brings her battered fiddle / We pull the chairs into a ring.” The slashes show line breaks. All three versions are also in the editable exercise below. Doorway is A, sing is B, fiddle is C and ring returns to B; doorway and fiddle are not intended to rhyme with each other.
The returning pair is still sing/ring, but the other endings no longer have to serve wall/hall. We gain a particular neighbour and an instrument, making participation more concrete. We lose the image of a crowd squeezing in, and the rewritten lines take different amounts of space to say. That is a real cost if a melody is already fixed. Try them in the intended phrase rather than squeezing syllables into place just to preserve the new detail.
In this four-line scheme, A and C each occur once. They do not promise another matching line later. You can also mark those positions with dashes when you want to emphasise that they are unpaired: – B – B. The planner supports both approaches. Choose one notation for your notes and judge the sound relationship yourself.
Map one version at a time in the planner.
Open the rhyme-scheme planner from this lesson's tool link. Paste only the four lyric lines of AABB into “One lyric line per row”, without the heading, labels or comparison notes. Click “Try AABB” and check that the visible pattern reads A A B B. These buttons assign letters to positions; they do not analyse the text. Clicking “Try ABAB” on the same words will label them ABAB even when the endings still rhyme AABB.
Replace the text with the ABAB version. Editing clears the previous labels, so apply “Try ABAB” again and check the actual endings. Repeat with the ABCB version and “Try ABCB”. Use each line's sound-family menu to change a label if your intended pronunciation or a rewrite calls for it. Choose a dash for an unpaired ending, or “Clear labels” to start the map over. The planner displays the first 32 rows; these four-line tests stay within that limit.
Save each labelled comparison with “Download labelled lines”. The file is named rhyme-scheme.txt, so rename your saved copies AABB, ABAB and ABCB to distinguish them. “Download .txt” saves the lyric text without the sound labels. “Continue in workspace” also transfers the lyric text, with an explicit choice to load it; no generation starts automatically. Download the labelled map separately if you want to keep it. The planner is a scratchpad: save before navigating away or reloading.
Choose a gain you can name and a cost you accept.
Speak or sing each version over the same comfortable pulse or melody. Listen for the returning endings, but also mark a rushed phrase, an unnatural emphasis or a confusing event. If you have to change the melody for a version, note that rather than treating the comparison as a test of rhyme alone. These examples have not been tested with a singer or audience; your performance is the next step.
For the clearest account of a whole room changing its plan, we would start with AABB. For the idea of neighbours arriving into music already underway, ABAB gives us that sequence using the same words. For one person actively joining in, ABCB adds the fiddle but asks us to check the longer phrases. Write your own decision as “I kept ___ because ___; I gave up ___; my next test is ___.” Save a runner-up. A useful outcome is a deliberate verse choice, not proof that one scheme wins every song.
Make three maps. Keep one reasoned choice.
Spend 2 minutes naming what the scene must keep, 4 mapping the three supplied versions in the planner, 4 drafting a different pattern for four lines of your own, 3 speaking or singing the alternatives against the same pulse, and 2 recording a choice and downloading your notes. If you have no draft, revise the supplied scene. Paste only lyric lines into the planner, one version at a time. Save this scratchpad before leaving it. Your output is a chosen four-line verse, a labelled map, one accepted tradeoff and one next test.
- Do my letters describe the endings I intend to connect, rather than merely repeat the preset?
- Have I named any changes to story order, detail, phrase length or melody?
- Can I explain why the chosen version serves this particular scene?
- Have I saved the labelled map separately from the lyric text and comparison notes?

A few useful answers.
What is the difference between AABB, ABAB and ABCB lyrics?
AABB pairs the endings of lines 1–2 and 3–4. ABAB pairs 1–3 and 2–4. ABCB pairs 2–4 while the first and third endings have different sounds. The letters describe sound relationships; they do not tell you which arrangement best fits a story or melody.
Can I turn AABB into ABAB just by swapping lines?
Swapping the middle two lines of a four-line AABB verse produces ABAB if the line endings keep their sound relationships. It can also change chronology, pronoun references or the logic of an action. Our example moves the neighbours' arrival after the singing begins. Check that change before keeping the reorder.
Does ABCB mean the A and C lines need rhymes later?
No. Within a four-line ABCB scheme, A and C mark different end sounds that occur once, while B returns. Later lines can reuse either sound if you choose. Dashes are another way to mark those two endings as unpaired in a planning note.
Will the rhyme planner rewrite my verse into a selected pattern?
No. Try AABB, Try ABAB and Try ABCB apply sound-family labels to the existing rows. They do not change words, detect pronunciation or suggest rhymes. Edit the lyric yourself, then check and reapply labels. Download labelled lines preserves the map; Download .txt and the workspace handoff carry the lyric text without labels.
