Construct
How to build a augmented fourth 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 augmented fourth from C3. Outcome: F#3
1.
A Augmented fourth uses
4 naturals.
Example: C3 ↠ D3 ↠ E3 ↠ F3
Example: C3 ↠ D3 ↠ E3 ↠ F3
2.
A Augmented fourth has
6 semitones between the notes.
Example: C3 ↠ C#3 ↠ D3 ↠ D#3 ↠ E3 ↠ F3 ↠ F#3
Example: C3 ↠ C#3 ↠ D3 ↠ D#3 ↠ E3 ↠ F3 ↠ F#3
