My son has been working on several classical pieces over the past few years or so. The Bach Cello Suites, Eccles Sonata in G Minor, Scarlatti and Marcello Sonata in G major. The solo pieces like the Bach and Scarlatti don't have any accompaniment so practicing and performing don't require you to adjust to another musician. But the other pieces have piano accompaniment and I was wondering how some of you have approached these types of compositions? Do you record a live accompanist? Use midi? Something else?
