A simple, quick and easy way to hear a concert pitch for any written note or piano key you play.
Quickly transpose for instruments in Ab, Eb, Bb, F, G, D, A, E.
Quickly view any pitch in Treble, Alto, Tenor or Bass clef.
See where written pitches lay on the piano keyboard.

- Be able to write down that melody other musicians can play it.
- Plunk out a melody without needing to be fluent in reading music. Just match written notes between Note Names & Pitches and your music.
- If you read music but don’t know the piano well, just choose a written note and it will play the pitch for you, give you the name of the note, and show you where it is on the piano.
- It’s also handy for any musician who regularly plays in ledger lines, Alto or Tenor clef, or simply needs a pitch every once in a while. String players, and a-cappella vocal groups could all find this indispensable.

Simply click / drag up and down on the staff to select the note, drag right for sharp, left for flat, or drag up and down near either edge for constant sharps or flats.
When playing the keyboard; use two fingers to scroll the keyboard, click to play notes, click & drag to glissando. When you glissando up, notes will be notated in sharps, when you glissando down, notes will be notated in flats. When you click specific notes they will be notated in the most common accidental for that note. ie: Eb rather than D#, F# rather than Gb.

Simple. Quick. Easy.
