Construction of Pentatonic and blues scale
The pentatonic scale and the blues scale are often
used for the blues, but are also frequently used in
the commercial and the rock. Familiarize yourself with
the sound, which can help you recall the arrangement
of notes so that you can distinguish them when you hear
them executed or carried by other guitarists.
Blues scale minor and Pentatonic
The minor blues scale, is made up
of seven notes (see graphics ). The first note is the
tonality of the scale.
It's followed from 1 tone 1/2, 1 tone, 1/2 tone, 1/2
tone, 1 tone 1/2, 1 tone.
The pentatonic scale minor, look like
the blues scale. The difference is that for the pentatonic
scale minor, you have to remove the fourth note (that's
in red, is the 1/2 tone). Thus, the pentatonic scale
minor is made up like that: the first note is the tonality
which is followed from
1 tone 1/2, 1 tone, 1 tone (1/2 tone +1/2 tone), 1 tone
1/2, 1 tone.
Blues scale major et pentatonic major
The blues scale major is made up of
seven notes (see the lower graph). The first note is
the tonality of the Scale.
It is followed of 1 tone, 1/2 tone, 1/2 tone, 1 tone
1/2,1 tone, 1 tone 1/2.
The pentatonic scale major is formed
about in the same way except that it is necessary to
remove the third note of the range blues scale (that
which is in red, is the 1/2 tone). Like the other scales
of which I spoke, the first note gives its tonality
and is followed of
1 tone, 1 tone(1/2 tone +1/2 tone), 1 tone 1/2, 1 tone,
1 tone 1/2.
It should be noted that:
The scale positions
It is thus to important to remove the notes D # (that
in red) in positions Ci-low, for the scales
pentatonic major et pentatonic minor.
For the scales of blues major and minor,
they are the same positions, but it is necessary to
include the note D # in red.
In order to know the other positions for the other
tonality, you only have to make the transpositions.
Now here are ten positions for the scales in tonality
of the A minor and C major.

Examples of pratice the scales
Here a way of carrying out the scales:
Initially, you carry out the second note you return
to the first, the second, you
make the third, then you reconsider the second, the
third and you make then
the fourth... You make all the note in this way. You
always reconsider the
preceding note. You can listen below the examples in
midi files and also
see the Fingering
Here two musical funds which will be able to help
you to practice your improvisation. These two midi files
were created with the JAMMER program. It is a program
very interesting for the improvisation. The first file
is a major one and the second one is minor.
Then, I say to you: " Good practice and see you
