Overview

A real grand piano you can play right in the chat. Ask for any chord (C, Am7, Bbmaj7, F/A and more) or scale (major, minor, pentatonic, blues and the modes) and HitJam lights up the right keys, spelled the way a musician would write them. Press Play to hear it, tap the keys, or play along with your computer keyboard: every key shows the letter that plays it. Learning a song? HitJam teaches public-domain classics note by note: the next key glows and waits for you, with right hand, left hand and both hands to work up through. The sound is a recorded concert grand, played on your own device. No account, no ads, and nothing you play is sent anywhere. Want the full instrument, other sounds or your MIDI keyboard?

Tools

show_piano_notes

ChatGPT
Light up specific notes on a playable piano, for intervals, voicings, inversions or any set of keys a chord or scale tool cannot express. Notes use scientific pitch: middle C is C4; sharps "#" and flats "b" are fine (e.g. "Eb4").
