Find a Dealer


The King 1121 mellophone is a highly responsive instrument that provides a powerful solo alto voice. Equally proficient in section work, it produces a full, rich sound that blends extremely well. The all-new mouthpipe and bell designs increase projection and power of the 1121's sound and the 1st slide thumb saddle and 3rd slide finger ring allow for easy intonation adjustments. Nickel plated pistons provide smooth, quick action and unmatched durability. The heavy duty marching case is designed to be stackable to minimize space requirements.
