A lesson on Giuliani Arpeggios No.18, 19, and 20 for classical guitar from 120 Arpeggio Exercises for the Right Hand, Op.1 by Mauro Giuliani (1781-1829). My lesson covers some technique tips, fingering concepts, and the double rest stroke in the thumb often used in these patterns.
These 120 arpeggios and the 100 open string arpeggios I mention are from my book Classical Guitar Technique: Essential Exercises, Scales, and Arpeggios.
The other video on how to practice the 120 arpeggios is below or at this lesson post.
Below is a specific lesson on planting in the right hand via this lesson post.
