What is the Minor Blues Scale?

The Minor Blues Scale Bass Lesson – > In the previous lesson we covered the Minor Pentatonic scale. Recall that the minor pentatonic is comprised of the roots, 3rd, 4th, 5th, and 7th of the minor scale. Below is a C minor pentatatonic:

The Minor Blues scale is the same as the minor pentatonic with one more note – the Flat 5th. So the minor blues scale consist of the the roots, 3rd, 4th, 5th, flat5, and 7th of the minor scale. Below is a C minor blues scale:

Minor Blues Scale Fingering

The scale can be played using a 4-fret span pattern. This pattern can be applied anywhere on the fretboard except when playing with open strings, or when playing more than one note on a string (see Intervals section below). To play this pattern, use the following fingering:

  • High Root – 1 finger (index)
  • Flat 3rd – 4 finger (pinkie)
  • 4th – 1 finger (index)
  • Flat 5th – 2 finger (middle)
  • 5th – 3 finger (ring)
  • Flat 7th – 1 finger (index)
  • Low Root– 3 finger (ring)

Minor Blues Scale Steps

The minor blues scale is constructed with these steps (intervals) between notes: Whole 1/2, Whole, Half, Half, Whole 1/2, Whole. Below is the C minor blues scale showing the steps between each note – W1/2=Whole and One Half Step, W=Whole Step, H=Half:

Knowing the intervals can help when you don’t use the 4-fret span fingering – playing on open strings, playing more than one note on same string, etc.

Why Is It Blue?

This scale is called a blues scale because it contains the “blue notes” of the major scale. The blue notes of major scale include the flat 3rd, flat 5th, and flat 7th. Below is a C major scale with the blue notes in blue:

When the blue notes are played as part of the major scale or within major chords they create that distinctive “bluesy” sound.

This is pointed out because a lot of times the blue notes are not used as the main bassline throughout a song. Instead they are more often played as part of a major scale bassline to add a bluesy sound to a song.

Applying the Minor Blues Scale

The minor blues scale is of course used when playing blues style music. You will most commonly hear it played throughout segments of blues songs – instead of using it throughout the entire song. Often the blues scale is played to emphasize major chords played with a blues chord progression. Often the blue notes are played as part of a major scale bassline to add a bluesy sound to a song.

The scale is also used extensively in rock, funk, and R&B styles of music. You will hear a lot of riffs in rock and funk that are using the minor blues scale. As with other minor scales and chords, the blues scale creates a darker sound that works well with heavier sounding riffs. Again, the blue notes are often played to clash with major chords to create a distinctive blues sound.
