Audio assigments from my "Introduction to guitar" course at Coursera.

3.3 Part 3

3.1 Part 1

3.4 Part 4

A major scale in 4th position, for two octaves.
At 88 beats per minute
At the end I've added the same scale played as fast as I can, just for fun :-)

4.5 A major scale 4th pos 2 Octs

G major scale in first position, for two octaves. 
At 88 beats per minute

4.4 G major scale 1st Pos 2 Octs

C major scale in first position, for one octave.
At about 200 beats per minute.
(I enjoyed the sound of this scale, so I've practiced it till I played it fast, I haven't used a metronome while playing this one, so I don't know the actual bpm, but I've calculated it is near 200bpm)

4.3 C major scale 1st Pos 1 Oct

A chromatic scale in 5th position.
At 88 beats per minute.

4.2 A Chromatic 5th Pos

G chromatic scale in first position, with open strings.
At 88 beats per minute.
