What you'll learn

Voicings · voice-leading · harmony · rhythm · repertoire

Left-hand voicings

Rootless A/B voicings, drop-2, drop-3, drop-2&4 and clusters — see every chord tone light up on the keys and compare them side by side.

Voice-leading

Watch the smooth motion between chords: held common tones and minimal movement of the guide tones (the 3rds and 7ths) through a progression.

ii–V–I in every key

Major and minor ii–V–I, tritone substitution and reharmonisation — transpose to any key with one click and hear the difference.

Chord-scales & modes

Mixolydian, Lydian dominant, altered, whole-tone and diminished scales mapped onto the keyboard with chord tones, tensions and avoid notes colour-coded.

Comping & rhythm

Swing and Latin comping patterns shown on a rhythm strip and played back with the voicings, so you internalise the feel.

Right-hand lines & standards

Bebop lines and enclosures in standard notation, plus real jazz standards as voice-led chord changes you can transpose and play through.

How it works

Built for the ear and the eye

Real sampled piano — every voicing and chord plays back with a genuine acoustic piano sound.
Music notation — right-hand lines rendered on a proper staff (VexFlow).
Interactive keyboards — click any keyboard to hear that chord; voice-leading lines connect the moves.
Transpose freely — take any lesson or standard into any key instantly.
Guided syllabus — lessons are ordered by a jazz-harmony curriculum with prerequisites.
Light & dark themes — and a layout you can flip for left- or right-handed use.
Bilingual — full English and Czech; jazz terminology kept in English in both.
Free & in-browser — nothing to install; open it and play.
