A little room for music
Your keyboard.
A real piano.
Explore a melody, hold a chord, follow your ear.
A piano across the middle row.
White notes use A S D F G H J K L ; ". Black notes use W E T Y U O P in the row above. Gaps follow the piano: there are no black notes between E–F or B–C. No Shift needed for the quote key. Hold multiple keys for chords.
Make space for the sound.
Hold Space for sustain, or click Sustain to latch it. Use ← / → to shift octaves and Esc to silence everything. Some computer keyboards limit simultaneous key presses.
