Frans Vester was a pioneer in the field of old instruments and the first flautist to record Mozart's concertos on a classical instrument, under Frans Brüggen's baton. His book supplies a model for an approach to Mozart's music in this day and age. Subjects such as articulation, tempo, ornaments, cadenzas and suchlike are addressed on the basis of eighteenth-century sources. Because of its practical approach, this book is a must for everyone interested in the performance practice of the classical era.
