LESSON 2
The Blues Changes. Melodic movements around a first steps of the harmonic functions
 
Bb Blues. The main objective of the second lesson learn to navigate the Blues Changes and also to build musical phrases using only various types of melodic movements around a first steps of the harmonic functions, using the steps the Minor Pentatonic Scale. Blues Changes a kind of verse in blues, which consists of three strings, each string consists of two two-bars phrases - "question" and "answer." The twelve-bars Blues Changes consisting of six musical phrases, and the culmination of falls on the ninth and tenth cycles that is the fifth phrase, located at the beginning of the third string. Not hard to guess that such form is interconnected with the traditional form of the poetic text of blues. Those who are already familiar concepts: Tonic (T), Subdominant (S), Dominant (D), will be understood by the following tables:

And yet I remind you that the harmony and harmonic functions exist to create a time-varying harmonic voltage. Function corresponds to the calm position of the tonic, subdominant function breaks the balance and creates tension, and the function of the dominant carries maximum voltage that requires resolution that is return to a state calm and balance. This gives us a harmonic sequence that creates musical energy. But we will not more be distracted, and will continue to practice exercises.
 
All exercises of the second lesson uses only Minor Pentatonic scale. The first exercise consists of three pairs of Blues Changes - one listening example, then in the next repeats exactly the same thing. The first example consists of long notes corresponding to the length of phrases and two-bars first steps of the harmonic functions indicated in the table in green (barlines are shown in black). In a second example, the same notes added lower melodic movements around a first steps of the harmonic functions and upper in the third 
 
 
 
In the second exercise we will have dialogue. On two-bars sound recording phrases, which begins with each bluesy string matching "question" and you will be required to play "answers".  I can recommend the following in advance: as much rhythm and as little as possible melodic movement, that is make the most of different rhythms on the central tone (in the present case, the first steps of the harmonic functions) and add a little bit lower and upper melodic movement around of the central tone, of course using only the Minor Pentatonic scale steps, for the first experience start and end phrases on central tone, limit yourself to a range of one octave, not move on a fifth step down and not move on a the first step up, build "answers" the first two blues strings or on the same rhythmic and melodic formula that "question", or variations on this formula  
 
 
 
In the third exercise, we change roles and you have to play "question", and listen recorded on a playalong "answers". Of course it can be done fully only in real-time live "interlocutor", but now more important that you played phrases corresponding harmonic functions "question" 
 
 
 
The final fourth exercise of the second lesson consists of the dialogues with himself, you and I will take turns playing for two interlocutors on a whole Twelve-bars Blues Changes, ask yourself "question" and give an "answers" for yourself. Of course it's like schizophrenia, but has historically been a blues form, although sometimes talk to myself even useful and interesting, there is a good chance to discover something new.  Three tracks in a row, of which the first and third I begin, and the second you start
