Experience the next generation of Orff instruments with the innovative SONOR SMART Series.

The SMART Series was developed through extensive acoustical research to help music educators get better sound, smarter storage, and greater classroom efficiency. Every design feature—from the acoustically optimized resonance chamber to the integrated accessory storage—was created to improve both teaching and student performance.

Why Teachers Choose the SMART Series Alto Metallophone

The ASM 10 provides the rich middle voice that helps connect soprano melodies with bass accompaniment. Alto metallophones play a critical role in creating fuller harmonies, borduns, ostinatos, and balanced ensemble textures while offering the portability and innovative classroom features that make the SMART Series unique.

• Warm, sustained alto tone for harmony and accompaniment
• Lightweight construction makes classroom transport easy
• Integrated riser improves playing comfort and posture
• Stackable cabinet maximizes classroom storage space
• Accessory Garage stores accidental bars and mallets inside the instrument
• Excellent for Orff Schulwerk, elementary music, and ensemble instruction

SMART Series Innovation

Every SMART Series instrument features an individually engineered acoustical chamber beneath each sound bar. This innovative design creates a more focused tone, improves resonance, and reduces unwanted vibrations for greater musical clarity during classroom performances.

The redesigned mounting system features durable, shatterproof pins that interlock beneath each bar instead of extending above it. The result is a more secure instrument during transportation and active classroom use while still allowing bars to be removed easily when needed.

The built-in Accessory Garage provides convenient storage for accidental bars and a pair of mallets directly inside the resonator box, helping keep classrooms organized and reducing misplaced accessories.

Educational Benefits

Alto metallophones are often considered the musical bridge of an Orff ensemble. Their warm, sustained sound supports melodies played on soprano instruments while reinforcing harmony and rhythmic accompaniment. Many teachers rely on alto metallophones for bordun patterns, chord progressions, ostinatos, and ensemble balance, making them one of the most versatile instruments in an elementary music classroom.
