【willie's Yamanashi JAPAN aquarius SOLO】 This is a mouthpiece from willie's, which boasts high quality and a rich lineup, mainly for trombones. It is the signature model of Hiroyuki Odagiri (former principal of the Tokyo Metropolitan Symphony Orchestra), the popular "aquarius". This model is a lightweight version of "aquarius", offering greater freedom. It retains the characteristics of "aquarius", such as the exceptional resonance in the mid-low range that defies the conventional 6-1/2 size, and the ease of control in the high range, while achieving a lighter blowing feel. This mouthpiece is recommended for orchestras, ensembles, and solo performances.
