This series contains 1 book of 8 pieces and has been created by Andy out of a need for beginner level clarinet trios that have been designed for beginner level players that sound like more complex, professionally arranged pieces. The ADVANCED level book in this series is confined to the range of E1 to D3 and is scored so that semi-quavers are the quickest note values within each piece, although only one piece in the book uses semi-quavers and this is a rather slow piece. This level contains more advanced level syncopation, an assortment of accents, dynamic markings and slightly more challenging fingering pattern challenges than the intermediate books in this series. The pieces are longer than the intermediate level pieces and contain stylistic challenges and have been arranged with more complex harmonic textures in mind to give the pieces a professional luster. There are eight pieces in this book and you can listen to audio samples for some of the pieces in the description of this product.
