In these volumes, the musical experience of two-part playing is further enriched by the use of different recorder types: where indicated, the lower part can be played not only on soprano recorder but also on alto, tenor, or even sopranino recorder. Some pieces include harmonic indications, so an accompaniment can be improvised alongside the two recorder parts. The process of learning and practising is additionally supported by a fingering chart and articulation marks for tonguing, with new musical elements highlighted in the score.
