  • There are three types of minor scales - Natural minor, Harmonic minor and Melodic minor.
  • Harmonic minor - Raised 7th
  • Melodic minor - Raised 6th and 7th
  • In the melodic minor, you only raise the 6th and 7th when going up. You use the natural key when going down.
  • There are 7 modes in total. The major and minor are just two of the modes that are the most common.
  • There seven modes - Ionian(Major), Dorian, Phrygian, Lydian, Mixolydian, Alolian(minor), Locrian.

  • A geometry represents a shape. Material represents the texture. You apply a texture to a geometry to create a mesh.
  • A geometry just defines the mathematical rules of a shape and hence can be reused.
  • A triangle is the smallest building block in the threejs and probably all other 3d modeling tools as well.
