One technique that is overlooked when transposing music - that maybe is interesting - is using clefs to transpose. Suppose I play alto sax (which I do!) and have sheet music written for a violin, in the concert key, in treble clef. If I want to transpose the music and play it on the sax, which is an Eb instrument, here's the trick: read the music as though it's written in soprano clef! A C in treble clef will be an A in soprano clef, which is indeed the correct transposition. Of course you still have to change your key signature. So if you can learn to be comfortable with a new clef, as was the standard when Bach was writing choral music, then this would be a great tool in the toolbox for transposing on the fly!
