Here is this week's transcription of Bach's 11th Invention in G Minor.
I didn't use any particular technique in this invention. There are lots of scales, and sometimes grouped scales, and the notes aren't always easy to reach, especially if you choose to raise the tempo. Keep in mind that this is my personal fingering. Also, remember you'll need a 7 string for the left hand but you can always play notes that need to be played on the 7th string an octave higher if you don't have one.
Hope this makes good practice.
