MAJOR INTERVALS
There are four Major intervals
 Major 2nd
 Major 3rd
 Major 6th
 Major 7th
(2, 3, 6, 7)
9
A major interval is determined by the
number of semitones it contains.
Major 2nd = 2 semitones
Major 3rd = 4 semitones
Major 6th = 9 semitones
Major 7th = 11 semitones
10
PERFECT INTERVALS
There are four Perfect intervals
 Perfect Unison
 Perfect 4th
 Perfect 5th
 Perfect Octave
(1, 4, 5, 8)
11
A Perfect interval is determined by
the number of semitones it
contains.
Perfect Unison = 0 semitone
Perfect 4th = 5 semitones
Perfect 5th = 7 semitones
Perfect Octave = 12 semitones
