Sonor Palisono GBKX 200 Bass Xylophone Chromatic Add-On

Expand your SONOR Palisono GBKX 100 Bass Xylophone into a fully chromatic instrument with the GBKX 200 Chromatic Add-On. Designed specifically for the SONOR Palisono Deep Bass Xylophone, this companion resonator box adds the chromatic notes needed for more advanced harmony, richer accompaniments, and expanded Orff ensemble repertoire while maintaining the outstanding tone and durability of the Palisono Series.

The bass section forms the musical foundation of every Orff ensemble. By adding chromatic notes, teachers gain greater flexibility for accompaniment patterns, key changes, bass ostinatos, and classroom arrangements without replacing their existing instrument.

Why Music Teachers Choose the GBKX 200

As music students progress, classroom literature increasingly calls for accidentals and harmonies beyond the C major scale. The GBKX 200 Chromatic Add-On gives educators an affordable way to expand the capabilities of their existing bass xylophone while preserving the consistent sound, appearance, and craftsmanship of the SONOR Palisono Series.

• Expands the SONOR Palisono GBKX 100 into a chromatic bass instrument
• Supports more advanced classroom repertoire and harmonies
• Provides additional flexibility for borduns, bass lines, and accompaniment
• Dedicated storage for the F# and Bb bars from the matching diatonic instrument
• Perfect for expanding Orff Schulwerk classrooms

Why Choose Palisono Fiberglass?

SONOR's exclusive Palisono fiberglass bars deliver the warm resonance educators expect from premium wooden instruments while providing exceptional resistance to humidity and seasonal weather changes. Because fiberglass is not hygroscopic, the bars maintain excellent tuning stability throughout the year, making them ideal for classrooms where environmental conditions fluctuate.

• Rich, resonant tone comparable to premium rosewood
• Excellent pitch stability in changing climates
• Precision overtone tuned to A440
• Highly durable for everyday classroom use
• Outstanding long-term performance for schools
