Transpose sheet music from a photo
Photograph a printed part. ScoreLens plays it in any key, plays a B♭ or E♭ part at the pitch it really sounds, and prints it for your instrument.
Three things people mean by “transpose”
- Play it in another keyMove the whole part up or down, for a singer's range or an easier key, and hear it at once.
- Hear a transposed part at concert pitchSay the page is for B♭ clarinet, E♭ alto sax or F horn, and it plays the notes that actually sound.
- Rewrite it for another instrumentTurn a flute or violin part into a page for B♭, E♭ or F instruments, and print it.
The rule for each instrument
- B♭ clarinet, trumpetWritten a major second above concert pitch
- E♭ alto saxWritten a major sixth above concert pitch
- F hornWritten a perfect fifth above concert pitch
- B♭ tenor saxWritten a major ninth above concert pitch
Why, with charts you can listen to: concert pitch and written pitch, and the transposition chart.
Questions
Can I transpose sheet music from a photo?
Yes. Photograph a printed single-line part, and ScoreLens reads it. Then play it in another key, or print it rewritten for another instrument.
How do I turn a concert-pitch part into a part for my B-flat trumpet?
Photograph the concert-pitch part, for example a flute or violin part, and print it for B♭ instruments. The new page is written a major second higher, so it sounds right with the others. E♭ and F parts work the same way.
How do I hear my clarinet part in concert pitch?
Tell ScoreLens the page is written for B♭ clarinet. It then plays the pitch the clarinet actually sounds, a tone lower than written, which is what the band and the piano hear.
Can I print the transposed part?
Yes, as a PDF. On the free plan it carries a small “Transposed with ScoreLens” line; Pro takes it off.
Can I get parts for the whole section at once?
Yes. From one page, print parts for C, B♭, E♭ and F instruments together, plus alto clef for viola and bass clef for cello or trombone when the page is a single line.
What can't it transpose?
Anything it can't read: two voices on one staff, handwriting and tablature. It is best on printed parts with one line on a staff, and reads piano too.
