Below is a table of basic musical intervals. In addition to the name of the interval and the number of halftones you will find a short name and an example built on C note. After that, intervals are grouped into perfect consonances, imperfect consonances and dissonances.
Perfect consonances | |||
---|---|---|---|
Interval name | Number of semitones | Short name | Example |
perfect unison | 0 | P1 | c-c |
perfect fourth | 5 | P4 | c-f |
perfect fifth | 7 | P5 | c-g |
perfect octave | 12 | P8 | c-c1 |
Imperfect consonances | |||
Interval name | Number of semitones | Short name | Example |
minor third | 3 | m3 | c-d# |
major third | 4 | M3 | c-e |
minor sixth | 8 | m6 | c-g# |
major sixth | 9 | M6 | c-a |
minor tenth | 15 | m10 | c-d1# |
major tenth | 16 | M10 | c-e1 |
minor thirteenth | 20 | m13 | c-g1# |
major thirtheenth | 21 | M13 | c-a1 |
Disonances | |||
Interval name | Number of semitones | Short name | Example |
minor second | 1 | m2 | c-c# |
major second | 2 | M2 | c-d |
minor third | 3 | m3 | c-d# |
tritone | 6 | TT | c-f# |
minor seventh | 10 | m7 | c-a# |
major seventh | 11 | M7 | c-b |
minor ninth | 13 | m9 | c-c1# |
major ninth | 14 | M9 | c-d1 |
