The Fritz Magg Musical Score Collection contains some 475 items in 44 boxes. Most interesting among those are his transcription of the Caprice no. 15 by Nicolo Paganini and a unique cello method, "A varied routine of practicing the 'Moto Perpetuo' by N. Paganini, a set of exercises arranged for cello. Magg, who devoted his lifetime to the study and teaching of Bach, left 32 editions of the unaccompanied cello suites, including a rare Alexanian edition. His particular performance annotations both in these Bach editions and in much of the standard repertoire are an invaluable part of this collection.
