iTranspose allows you to transpose a sequence of notes between keys.

Enter a sequence of notes using the on-screen keyboard. Listen to the playback to verify you've got the right notes. After placing a note, drag up or down on the stave to move it in real-time. Then select your source and target key signatures, and transpose up or down between keys.

Great for transposing quick runs - for example, if you want to play a fill from a horn on a 'cello!

Supports treble, bass, tenor and alto clefs, with major and minor keys. Supports saving note sequences as screenshots saved to your photo library or sent by email.

Please note - this is not a general purpose music application. It is designed specifically for transposing short sequences of notes - so you can pull it out your pocket on the spot and get something transposed within a few seconds. It is not designed for transcribing or composing.
