Intervals can be described as Major (M), Minor (m), Perfect (P), Augmented (A), and Diminished (d).
Intervals come in various sizes: Unisons, Seconds, Thirds, Fourths, Fifths, Sixths, and Sevenths.
2nds, 3rds, 6ths, and 7ths can be found as Major and Minor.
Unisons, 4ths, 5ths, and Octaves are Perfect.
let's look at the Chromatic Scale:
C, C#, D, D#, E, F, F#, G, G#, A, Bb, B, C
C to C# is a Minor second
D to D is
a Major second
C to D# (also called Eb) is a Minor Third
C to E is a Major third (we use these a lot)
C to F is a
C to F# is a Diminished 5th
C to G is a Perfect 5th
C to G# is an Augmented 5th
C to A is a Perfect
C to Bb is a Minor 7th
C to B is a Major 7th
C to C is an Octave
(it continues on after the octave to 9th,
