KGUmusic Capella C Trumpet

The KGUmusic Capella C Trumpet is a meticulously crafted instrument tailored specifically for classical musicians. Honoring the traditional KGUmusic approach to brass design, this model was developed with close input from professional trumpeters and refined through extensive testing. The result is a trumpet that offers superb tonal integrity, responsive articulation, and nuanced dynamic control—essential for the modern classical performer.

Materials & Acoustic Character

The Capella C employs a carefully balanced combination of red brass and yellow brass, selected not only for their acoustic qualities but also for their contribution to the instrument's feel and responsiveness.

• The red brass bell enhances warmth and depth in the sound profile, ensuring lyrical phrasing and resonance across the range.

• The yellow brass leadpipe and tuning slides provide structural clarity and fast response, supporting a focused tonal core and stability in articulation.

• The ML bore (0.460” / 11.7 mm) offers the ideal blend of resistance and openness, allowing the performer to shape their sound with control and ease.

The resulting tone is refined, expressive, and precisely aligned with the demands of classical repertoire—from delicate chamber works to full orchestral passages.
