Thank you for viewing. This is a DAC original euphonium cushion for seated playing. It was used for about a year while wrapped around the instrument, so the non-slip material is slightly worn, but it is in good condition and does not affect use. ・Product Features Improvement of playing posture When playing the euphonium while seated, it is used by placing it between the thighs and the instrument to stabilize the instrument. By using this, the burden on the arms and wrists due to the weight of the instrument is reduced, and you can concentrate on playing in a comfortable posture. Supports stable playing By stabilizing the posture, you can hold the instrument in a natural position, and your breath will flow smoothly. As a result, the tone and resonance improve, leading to higher-quality performance. Safe with non-slip The back has a non-slip material, so you don't have to worry about the cushion slipping during performance. The instrument and the cushion are firmly fixed, increasing stability. ・Product Details Manufacturer: DAC Original (DAC, a wind instrument specialty store) Condition: Excellent condition Size: L size (6cm thick)
