In this first lesson I'll try to explain a little bit about how to play 3 octave scales. In the next 2 lessons I will post different patterns and intervals you can use to play your scales in a more interesting way. Remember that this are merely technical workouts that should be turned into music after you've internalized the material.
In the image below we find three different examples with notation and tablature.
Example A is a G major scale played in 2 octaves. Look that we start in the sixth string and don't shift upwards in any moment. This position (look in the tabs) benefits position playing. It alters between 2 and three notes per string. This shouldn't be a problem and all notes should sound equally. Playing it with a metronome is a must.
If we would like to play a G major scale that covers 3 octaves we couldn't use this same position. Example B shows that if we stick to this position we would end up by playing one entire octave on one string. This isn't bad at all but its not technically efficient (I practice A LOT of single string improvisation but this lesson is focusing on scales and efficiency rather than on single string phrasing.
To play a G major scale that covers 3 octaves in a comfortable and logical way we need to play it in a mix of horizontal and vertical shifts. Example C shows that we star combining 4 and 3 notes per string. The tablature provided shows how to execute the fingerings but it could vary, just remember to keep the same logic of playing in a uniform way and not playing more than 4 notes per string.
I hope this exercises work for you and I will be posting the next lesson soon!
