How to build a tredecime interval?
To construct an interval correctly you must always use two steps.
- Count the amount of naturals used
- 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 tredecime from C3. Outcome: A4
1.
A Tredecime uses
13 naturals.
Example: C3 ↠ D3 ↠ E3 ↠ F3 ↠ G3 ↠ A3 ↠ B3 ↠ C4 ↠ D4 ↠ E4 ↠ F4 ↠ G4 ↠ A4
Example: C3 ↠ D3 ↠ E3 ↠ F3 ↠ G3 ↠ A3 ↠ B3 ↠ C4 ↠ D4 ↠ E4 ↠ F4 ↠ G4 ↠ A4
2.
A Tredecime has
21 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
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
