Mark On The Iron has introduced Musician’s Little Helper 1.0 for Mac OS X. It’s a tool designed to “help inspire your next classic” and to “help spark those first few notes that can create a killer riff or beautiful melody.”

To use Musician’s Little Helper, you first pick the scale you want from a list of 68 available. Pressing the Random button will jumble up six individual notes relevant to the chosen scale. The notes are placed in spaces on the main screen, so you can see them and play them.

You can experiment with changing the order of the different notes, and even add more by dragging them from the keyboard into the free empty spaces, creating a longer series of notes to play back. You can even make a loop with them by adding the loop icon into a free space.

Additionally, Musician’s Little Helper aids in actually learning scales, by highlighting on a keyboard which notes belong to each scale. You can adjust the playback tempo using the interface’s slider

Musician’s Little Helper 1.0 costs US$0.99 USD, requires Mac OS X 10.5 or higher and is available worldwide through the Mac App Store in the Music category. Musician’s Little Helper is also available for iPhone and iPad.
