Classical Piano
Europe, 1700–1930
Studies, sonatinas and character pieces, read from the first printed editions.
Music the world handed down, for every instrument: jigs and reels, rags and études, spirituals, kritis and dances in seven.
Every piece is read from its original printed edition. Hear it, take it into your key and onto your instrument, loop the bars that trip you, then play it back and the microphone marks each note.
Choose a plateSand on a bowed metal plate gathers where the plate stands still. Each room has its own plate and its own note: press the note to hear it, and watch the sand find its figure. Two rooms are open; the rest are being written now.

Arban's Complete Method and Clarke's Technical Studies, page by page.
Beside every modern copy sits the page it was read from: Burgmüller's Arabesque as Schirmer engraved it, the Maple Leaf Rag from John Stark's 1899 plates. If you doubt a note, look at the engraving yourself.

Pick any of the twelve keys. Pick your instrument and the part is written for it: a trumpet or clarinet in Bb reads a tone higher than it sounds, an alto sax in Eb a major sixth higher, a horn in F a fifth higher. The sound stays where the band hears it.
Turn on the microphone and play along. Each note turns right or wrong as you play it, with how many cents sharp or flat you were, so you can hear and see your tuning settle.
