Shouldn't all music intervals have five names?
Shouldn't technically all intervals have five names? (Maybe with few exceptions where it goes below zero semitones but still I can't see why it can't go below zero semitone when it can be played) With these five possible cases: 1. ♯Note-♭Note ( n semitones ) 2. ♯Note-Note or Note-♭Note (n+1 semitones ) 3. Note-Note ( n+2 semitones ) 4. Note-Note♯ or ♭Note-Note ( n+3 semitones ) 5. ♭Note-♯Note ( n+4 semitones )
