An interesting set of two manuscripts, both written in 1722 by an otherwise unknown person. The first manuscript contains an overlong ‘Fantasia’ for organ or harpsichord, which modulates through all 24 keys; the second is a treatise describing several tuning systems, (just intonation, the 31-tone system). With transcriptions and translations of the German texts.
