The pentatonic and blues scales are fun to play around with and give you a certain bluesy sound.
Minor pentatonic has one less note than the blues scale, so they’re practically the same scale.
1,-3, 4, 5, -7
with the minus sign meaning ‘minor’
is the minor pentatonic.
1,-3, 4, #4, 5, -7
is the blues scale.
In the key of Bb (concert), the blues scale on tenor sax is
C, Eb, F, F#, G, Bb
on alto in Bb (concert), it’s
G, Bb, C, C#, D, F
To check out an application of the minor pentatonic scale, you can look at the free lesson on the tune Cantaloupe Island which uses the minor pentatonic scale exclusively for the melody and in which you can apply the blues scale over improvisation.
