Questions
Transposing, explained.
Why do clarinet and trumpet parts need transposing?
B♭ instruments sound a major second lower than written. For a piece to sound right at concert pitch, the part has to be written a major second higher — that's exactly what the "B♭ clarinet / trumpet" button does.
Which interval for which instrument?
B♭ instruments (clarinet, trumpet, tenor sax): up a major second. E♭ instruments (alto sax, E♭ clarinet): up a major sixth. Horn in F: up a perfect fifth. For anything else, pick the interval freely.
Does the key signature move too?
Yes. The key signature is transposed along (C major becomes D major when you go up a major second), and every note is respelled to fit the new key. Rhythm, slurs and dynamics stay untouched.
Is this transposer really free?
Yes — with a free account, one page a day is free, and there’s nothing to install: you upload, transpose and download. More pages come with Pro or Lifetime.
Can I keep editing the result?
Yes — the MusicXML download opens in MuseScore (free), Sibelius, Dorico or Finale. Please double-check any measures the ledger flags.
