Thomas Viloteau via his youtube channel gives a lesson in right hand arpeggios of classical guitar. He discusses aspects of gaining control, variety to avoid the difficulty of repetitive motions as well as control the texture, keeping the hand stable, full plants, sequential plants. A nice basic lesson. If you’re looking for a technique book you can check out my review of classical guitar technique and exercise books.
