Construct

How to build a augmented tredecime 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 augmented tredecime from C3. Outcome: A#4

1.
A Augmented tredecime uses 13 naturals.
Example: C3 D3 E3 F3 G3 A3 B3 C4 D4 E4 F4 G4 A4
2.
A Augmented tredecime has 22 semitones between the notes.
Example: C3 C#3 D3 D#3 E3 F3 F#3 G3 G#3 A3 A#3 B3 C4 C#4 D4 D#4 E4 F4 F#4 G4 G#4 A4 A#4
