Modern clarinetists have a large repertoire available that demands an immense skill set. These skills range from the fine technical control required for Mozart to the guitar-like effects in Scott McAllister's music. Clarinetists must have these numerous skills ready at any moment, which can be a daunting task. Any student, young or old, is likely to ask, "What can I do to prepare for the technical demands of the clarinet's vast literature?" We, the authors, created Extreme Clarinet to combine the instruction of basic fundamentals, extended range, precise finger motion, precise and rapid single and multiple articulation, and circular breathing into one guide. By merging traditional methods with extended techniques, we hope to narrow the gap between the two and foster what can be considered contemporary clarinet technique.
