Description

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

6 tools agents can invoke

List the songs available for a piano lesson, with difficulty. Use when the user asks what songs they can learn.
list_piano_songs
Light up the keys of a chord on a playable piano, near middle C, correctly spelled. Accepts standard chord symbols: C, Cm, C7, Cmaj7, Cm7, Cdim, Cdim7, Cm7b5, Caug, Csus2, Csus4, C6, Cm6, C9, Cmaj9, Cm9, Cadd9, C5, and slash chords like C/G. Use when the user asks how to play, find or see a chord on piano or keyboard.
show_piano_chord
Show a playable grand piano in the chat with nothing highlighted. Use when the user wants to play or try a piano, or asks for a virtual/online piano. For a chord, scale, specific notes or a song, use the more specific tools instead.
show_piano
Light up a one-octave scale on a playable piano, correctly spelled, and play it upward. Scale types: major, minor, harmonic minor, melodic minor, major pentatonic, minor pentatonic, blues, dorian, phrygian, lydian, mixolydian, locrian, chromatic. Use when the user asks for a scale or mode on piano or keyboard.
show_piano_scale
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").
show_piano_notes
Teach a song on a playable piano, one note at a time: the next key lights up and waits for the user to press it, and Play performs it. Available songs (all public domain): mary-had-a-little-lamb (Mary Had a Little Lamb); twinkle-twinkle-little-star (Twinkle, Twinkle, Little Star); ode-to-joy (Ode to Joy); frere-jacques (Frère Jacques); amazing-grace (Amazing Grace). Only these songs are available; for any other song, say so and offer one of these instead.

How do I improve HitJam Piano's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
