The Music Rule
How To Use Educators Testimonials Students Improvisers Order


    Fits conveniently in your gig bag. THE MUSIC RULE is literally a horn players survival tool.
    No one has to transpose on the fly more than horn players. THE MUSIC RULE provides
    instant transposition with a simple slide.

    It's like having a chord book, a scale book, a mode book and a transposer all in one.
    Immediately locate interval relationships and the letter names of all notes in any chart, chord,
    scale or mode; in any key. You can then transpose that information to any other key desired.
