The ‘Scale’ class

class music_essentials.scale.Scale

Static class methods for building lists of notes according to pre-defined patterns.

classmethod build_scale(tonic, scale_type)

scale_type : str

The type of scale to build. Supported scale types are:

• ‘major’/’maj’: major scale
• ‘minor’/’min’: harmonic minor scale
• ‘natural minor’/’nat min’: natural minor scale

Returns:

list

The notes in the specified scale, in ascending order.

Raises:

ValueError:

If an scale type is provided.

TypeError:

If the tonic is not a Note., or scale type is not a string.
