Construct

How to build a major seventh 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 major seventh from C3. Outcome: B3

1.
A Major seventh uses 7 naturals.
Example: C3 D3 E3 F3 G3 A3 B3
2.
A Major seventh has 11 semitones between the notes.
Example: C3 C#3 D3 D#3 E3 F3 F#3 G3 G#3 A3 A#3 B3
