The CSGIII is seen as the clarinet to compete with the dominance of the R13. The clarinet looks great, It blows easily and has an even tone throughout. There is a lovely full sound and good resonance at the bottom of the instrument. The keys feel great under the fingers. The speaker key in particular is a great shape and is in a much more natural position. The intonation throughout is good with no bad notes. The upper register plays easily even up to top C.
