Fantastic F Mellophone!

The King 1121 Ultimate Series Marching F Mellophone is designed for advancing marching ensembles seeking superior projection, rich tone, and comfort for horn players. Featuring a 10.5" yellow brass bell and .468" bore, the 1121 produces a bold, resonant sound with ample volume for solos yet blends beautifully with other instruments. This King mellophone is destined to delight audiences and impress band directors.

Smooth Transition from Horn to Marching Field
The 1121's angled leadpipe provides familiar mouthpiece positioning for horn players while properly elevating the bell. King's innovative Dynamically Angled Mouthpipe alleviates embouchure challenges players often experience when switching between horn and mellophone. The result is a seamless transition to the marching field.

Power, Projection and Playability
With a large 10.5" yellow brass bell and .468" bore, the 1121 delivers a powerful tone with superb projection ideal for indoor marching ensemble performance to open stadiums. Its three nickel-plated pistons provide smooth, consistent action and corrosion resistance to withstand all playing conditions. A first slide saddle and third slide ring enable quick intonation adjustments on the march.

Built to Inspire
From the choice of lacquer or silver plate durable finish to the fixed bell brace, the 1121 is constructed to handle the demands of high-level marching. Reliable and resonant, this mellophone produces a bold, lyrical tone to thrill audiences and showcase your ensemble's talents. When only the best will do, choose the King 1121 Ultimate Series Marching F Mellophone.
