Sonor Meisterklasse GBKM 10 Deep Bass Metallophone

The SONOR Meisterklasse GBKM 10 Deep Bass Metallophone is the flagship bass metallophone in the SONOR Meisterklasse Series, delivering the rich, resonant foundation that every outstanding Orff ensemble needs. Featuring precision-tuned special alloy metal bars, a handcrafted six-chamber resonator box, and SONOR's legendary German craftsmanship, the GBKM 10 produces exceptional sustain, warmth, and tonal clarity for elementary music classrooms, universities, and professional Orff Schulwerk programs.

The deep bass voice anchors your ensemble, supporting melodies while helping students develop rhythmic accuracy, harmonic awareness, and confident ensemble playing.

Why Music Teachers Choose a Deep Bass Metallophone

While soprano and alto instruments often carry the melody, the deep bass metallophone provides the musical foundation that gives an Orff ensemble its depth and balance. Its warm, resonant tone reinforces harmony, supports rhythmic patterns, and helps students experience how bass voices shape the overall sound of an ensemble.

• Rich, resonant bass voice for Orff ensembles
• Exceptional sustain and projection
• Supports harmony and accompaniment
• Balances soprano and alto instruments
• Ideal for advanced elementary through university music programs

The SONOR Meisterklasse Difference

The Meisterklasse Series represents the highest level of SONOR Orff instrument craftsmanship. Each specially alloyed metal bar is precision tuned by hand to A440 for outstanding intonation and tonal consistency. Flexible rubber pins allow bars to be removed easily, while the six-chamber resonator box maximizes resonance and projection. Diatonic models include removable F# and Bb bars, and a convenient side-mounted holder keeps the extra bars organized when not in use.

• Premium specially alloyed metal bars
• Precision tuned by hand to A440
• Overtone tuning for rich bass resonance
• Six-chamber pine plywood resonator box
• Flexible rubber mounting pins
• Side-mounted accidental bar storage
• Note names stamped on every bar for easier music reading
