Lead sheet reading
Read a melody with the chord symbols over it, as on a real lead sheet, and play the left hand from the symbols: roots, shell voicings and guide tones, through ii–V–I, the twelve-bar blues and thirty-two-bar tunes in swing, bossa nova and ballad feels. Every chart is written fresh on your device and checked with a MIDI keyboard or a microphone. Levels 1 and 2 are free, no account needed.
About lead sheet reading
Where do the charts come from?
Your device writes each one when you ask for it, from a table of eight levels we wrote ourselves. The changes are the progressions chord-symbol harmony uses, written in the key of the chart, and the melody is made against the chord under it, so the strong beats land on chord tones. No published tune is used.
Where is the left hand?
Not on the page, as on a real lead sheet: you play it from the symbols. The level says what to play and where, for example the root of each chord in the octave from E2, and the check expects exactly those keys, so the left hand is checked even though it is not drawn.
How does it check my playing?
A MIDI keyboard tells it exactly which keys you pressed. With a microphone, the sound is analyzed on your own device and never uploaded; with both hands playing at once, a microphone can return more “couldn’t tell” notes than usual. Either way the result is a count of the notes played right, wrong or missed, drawn on the melody. It is not a grade.
What does swing change?
On the swing levels the eighths are written plain, as in every jazz chart, and played long–short. The check expects the long–short timing, so playing them straight shows up as off time.
Is anything saved?
No result is saved, because the chart itself is never stored. The time you spend counts toward your practice record, and the level you choose is remembered on your account.
Which levels are free?
Levels 1 and 2 are open to everyone, with or without an account. Levels 3 to 8 are part of Pro.
