Overview

Coordinate representation of pitches

Pitches are represented by a combination of octaves and fifths away from Middle C

For example, the C#4 is represented as (-4, 7), and Db4 is (3, -5).

The benefit of this approach over a semitone-based system is that it is easier to keep track of enharmonic notes, and it also makes interval math much simpler.

• .new(octaves : Int32, fifths : Int32)

Instance Method Summary

• #*(i : Int32) : Coords
• #+(other : self) : Coords
• #-(other : self) : Coords
• #==(other : self) : Bool
• #fifths : Int32
• #octaves : Int32
• #to_s(io : IO) : Nil

  Same as #inspect(io).

• #value : Int32

  Returns the pitch offset from Middle C and can be used to calculate the pitch name
