Vizzutti Trumpet Sonority - 20 Adagios - Book & CD. Is a valuable addition to the series of study books by Allan Vizzutti, These twenty short compositions, which might all be described as Adagio, are ideal for practising lyricism, beauty of tone, natural phrasing, and smooth flow. The directions in the music, and in particular the enclosed CD - on which Allen plays all the pieces himself - serve as a guide to interpretation.
