Interactive C5

You should be able, when playing with the c5 to :

One click rotate circle

Rotation just takes the chord a (or many) fifth(s) further. Example : a Gm is a rotation of the minor chord, if the song is in Cm.

Major chord : It’s dominant major chord :

Switch to circle’s contrary

Every selected note will be unselected and vice versa. It can be useful cause it’s a classic transormation of a set in math. Having it done in one click could stimulate it’s creative application.

Moreover we will need a feature in the Open Phrase Dict to allow playnig outside of a scale. Playing outside a scale is an effect in which you deliberately only play what would be considered as being falses notes. Suggesting “outside” harmony to a scale can lead, again, to creative uses.

Diatonic scale : Opposite pentatonic scale :

Mirror circle

That’s another classic set math feature, but would it be useful musically ?
Note that 2 kind of mirror exist :

• Taking a “dot to opposite dot” mirror line
• Taking an “in-between dots to opposite in-between dots” mirror line. This one is less obvious but can lead to, for example, change a minor chord to a major one! So it may be more applicable.

Major chord : Minor chord :
