Construct

How to construct the diminished fourth interval?

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

1 • Count the amount of naturals used
2 • Count the semitone steps between the two notes

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

The following example is for a minor second from C3. Outcome: F3

1 • The diminished fourth spans 4 naturals.
C3  ↠  D3  ↠  E3  ↠  F3
2 • The diminished fourth has 24 semitones between the notes.
C3  ↠  D3  ↠  D3  ↠  E3  ↠  E3  ↠  F3  ↠  G3  ↠  G3  ↠  A3  ↠  A3  ↠  B3  ↠  B3  ↠  C4  ↠  D4  ↠  D4  ↠  E4  ↠  E4  ↠  F4  ↠  G4  ↠  G4  ↠  A4  ↠  A4  ↠  B4  ↠  B4  ↠  C5
