Song Compose and Transpose

About this app

This app is aimed at the musician who needs light-weight music performance note taking and already knows how to play all chords just by looking at their names, on any instrument. (For example: C9 or Abmin7) Does your singer ask: "Can we do this down a whole step?". Well now you can hit 1 button and say: "Yeah, I'm ready". - Allows maintaining all songs you play, and transpose their notes to any key with a key press. - Transposing separates the Chords in your notes from lyrics and other notes. Only the chords are transposed. - The chord modifiers are maintained after transposing. For example: All "A min/maj7add2" would become: "Ab min/maj7add2" if transposed a semitone down. - Hundreds of chord types supported, and any combination of modifiers. Examples: 7, 9, add2, m, m7, maj7, min7b5, maj/min7, sus4, #5b9, 9/11, slash chords, etc. - Change the font size so it's easier to see with your screen size. - Supports iPhone and iPad on both orientations. iPads feature a master-detail layout: all on one screen. - The "Add Chord" wizard contains all possible extensions which you can combine with the Key and the Chord Type. I always want to know what you think, and what you would like to see in this app. Please use the Feedback feature in the app to tell me what you think, or email: TransposeApp@gmail.com any time! Thanks, Alex
