Try these weird sounding multi-octave licks
Here’s a different kind of exercise that focuses on octaves. An octave is simply a repeat of the same note higher or lower. For example, an “A” played at the 14th fret of the G-String is two octaves higher than the A played on the 5th fret of the low E-String.
These exercises below were inspired by the Hungarian Rhapsodies by legendary classical pianist and composer, Franz Liszt. Liszt employed the same technique in one hand on the piano – why not try the same idea on the guitar?
Liszt’s technique was to play a note followed by a repeat of that note one octave higher. He then would repeat the same note at the higher octave, but using a different finger to position his hand for another note one octave higher. The following exercise on the guitar does the same thing:

In this example above, two different fingerings are shown. The first measure, the preferred, repeats the note on the D-string 5th fret with position and finger switches. The second measure achieves the same thing with the open string. The first fingering is preferred because we can move this technique anywhere on the neck!
For example, try this a-minor scale exercise with the same technique:

This is a tough lick to play quickly, but speed is not so important here. Just strive for playing it smoothly. Try not to get too mixed up by all the notes all over the neck. Concentrate on the low note and then the shape of the pattern. Simply repeat that pattern up the scale. Try to take the same pattern and apply it to a major scale.
For a really crazy challenge, try getting this G-note four-octave exercise up to a quick speed. It’s a little tricky, especially when repeating – there are three low G-notes which repeat. Played fast, it’s a neat-sounding lick:
