Intervals

The interval between two notes is calculated by the number of half steps between these notes.

Minor Second = 1 half step
Major Second = 2 half steps
Minor Third = 3 half steps
Major Third = 4 half steps
Perfect Fourth = 5 half steps
Tritone = 6 half steps
Perfect Fifth = 7 half steps
Minor Sixth = 8 half steps
Major Sixth = 9 half steps
Minor Seventh = 10 half steps
Major Seventh = 11 half steps
Octave = 12 half steps


To help demonstrate, listed below are the intervals each starting with the note "C"

Minor Second = C-Db
Major Second = C-D
Minor Third = C-Eb
Major Third = C-E
Perfect Fourth = C-F
Tritone = C-Gb
Perfect Fifth = C-G
Minor Sixth = C-Ab
Major Sixth = C-A
Minor Seventh = C-Bb
Major Seventh = C-B
Octave = C-C
