Create · Jazz charts

Jazz chord charts you can play and study: AABA, voicings, chord symbols, in real notation.

Type the assignment the way it was set. You get a chart in real notation: chord symbols printed above the staff, a voicing under each one that you can play, in the form you asked for. Press play to hear it, then keep changing it in words. Prompts work in any language.

Start free, no card needed. Your first piece is free.

The prompt
“48 bar jazz piano progression, chords only. no melody or basslines. write out chord symbols”

Say it the way your teacher wrote it.

Each score below came from the sentence beside it, typed into LalaScript by a real person. Nothing was fixed by hand.

The prompt
“write a melody using extended lines over Dm11 following the Dmixolydian scale. inspired by maiden voyage melody and other modal vampires melodies”

Open Water, Low Sun

Thirty-five bars for piano in D mixolydian over a one-chord vamp. The prompt asks for Dm11 on a mixolydian scale, which cannot both be true, so LalaScript kept the mode, voiced the vamp as a D sus chord, and said why.

The chart is where the conversation starts.

Every change is a sentence in the edit box, and every answer is a new version of the same chart. The old versions stay in the history.

You typetranspose to Eb for the alto

Set the assignment. Make the examples.

Write one worked example in the key you want to talk about, then another in a different form, and go through the voice leading together in class. LalaScript makes the material. The teaching, and the grading, stay with you.

205 rules from a musician's ear

Every rule the engine follows came from a musician listening and saying what a player would never write. Each one is guarded by a test.

Spelled for the key

Every bar adds up and every chord is spelled the way the key wants it. A chart on the stand reads like a chart, not a guess.

Jazz charts, answered.

Does LalaScript print the chord symbols on the chart?

Yes. A LalaScript jazz chart comes back with the chord symbols printed above the staff and the voicings written out underneath, so it reads as a chart and plays as written.

Can I choose the form and the chords?

Yes. Ask LalaScript for AABA, a 12-bar blues, or your own number of bars. If you write the chords out yourself, those are the chords you get, in your order. For progressions by Roman numeral, see the chord progression generator.

Can I change the chart after it is written?

Yes. In the LalaScript edit box you say the change in plain words, for example transpose to E flat or slow it down, and you get a new version of the same chart. Earlier versions stay in the history.

What can't the LalaScript jazz chart generator do yet?

LalaScript writes for one instrument at a time, so a combo chart with separate bass and drum parts is not there yet. It writes original music in a style, not arrangements of standards or songs by name.

Your chart is one sentence away.
