New slider option! The openings of the standard slider are 25% larger. The sound is full and loud. The professional-slider has a 2mm shorter action and is optimised for excellent tone control especially if you play soft pieces at lower volumes. The slider of the SYMPHONY can be changed easily and within 20 seconds. Both sliders are included in the package.

The recessed reedplates (1mm) are precision cut from anti-corrosive German silver. Hand-tuning of the 64 stainless-steel reeds, tight tolerances, and newly developed SEYDEL valves (with less adhesive than conventional valves) create an instrument with precise tone control and a rich sound with a tonal range of four full octaves.

The variant 'ALU' has a black anodized aluminium comb (total weight 438g / 15.5Oz), the variant 'ACRYL' has a translucent-green colored acrylic comb (total weight 362g / 12.8Oz). Both are CNC-milled and perfectly balanced.

Solid, die-cast, coated aluminium coverplates are screwed on individually providing a design that is widely-opened at the back for a balanced feel and dynamic, full, warm sound projection in all four octaves.

The comb accommodates the provided carrying strap, made from genuine leather and with a SEYDEL embossing, to securely harness the instrument. It can be attached either on the right or the left side of the SYMPHONY Grand Chromatic.

The SYMPHONY 'ACRYL' has a halfmoon-shaped mouthpiece. Both variants are silver-coated and screwed on from the backside of the comb to provide optimal playing comfort with no screw heads on the outer surface of the mouthpiece for better haptic properties.
