Transposing Instrument Context

B♭ instruments (trumpet, clarinet, tenor saxophone) read in F major to sound E♭ Major. E♭ instruments (alto saxophone, E♭ clarinet) read in C major to sound E♭ Major. Flat-key signatures are particularly comfortable for woodwind instruments designed around B♭ and E♭ transpositions.
