Construct

How to build a diminished third interval?

To construct an interval correctly you must always use two steps.

  1. Count the amount of naturals used
  2. Count the steps between de two notes

At first, and with easy intervals, this may seem unnecessary, but when advancing to more dificult intervals and musical keys they will become more mandatory.

The following example is for a diminished third from C3. Outcome: Cb4

1.
A Diminished third uses 8 naturals.
Example: C3 D3 E3 F3 G3 A3 B3 C4
2.
A Diminished third has 11 semitones between the notes.
Example: C3 Db3 D3 Eb3 E3 F3 Gb3 G3 Ab3 A3 Bb3 B3 C4 Db4 D4 Eb4 E4 F4 Gb4 G4 Ab4 A4 Bb4 B4 C5
