Yamaha Baby Grand Piano Comparison Chart: GB1K, GCB, GC1, GC2 and C1X

Yamaha’s baby grands start at 5 feet. The GB1K and the new GCB are the most compact; the GC1 and GC2 are the GC series; the C1X is the first model of the CX series, Yamaha’s professional line. This chart shows how they compare.

The Differences in Brief

• GB1K and GCB: both 5′ long. The GCB is the newer design, built at Yamaha’s Kakegawa factory in Japan with a V-Pro frame, a sostenuto middle pedal and Silent and Disklavier versions; the GB1K has a bass sustain middle pedal.
• GC1 and GC2: 5’3″ and 5’8″, with sostenuto pedals and Silent, TransAcoustic (GC1) and Disklavier versions.
• C1X: 5’3″, from the CX series: Ivorite and wood-composite key tops, CX series hammers and lid and fallboard locks.
• Length and sound: a longer grand has longer bass strings and a larger soundboard; each step from 5′ to 5’8″ fills a room more fully.

Yamaha Baby Grand Specifications

Specifications from Yamaha (Yamaha’s GB1K, GCB and CX series pages; GC1 and GC2 sizes from Yamaha’s Silent Piano specifications, which list the same cabinets). Yamaha currently publishes no weight for the GC1 and GC2.

Which Is Right for You?

Measure the room first: allow the piano’s length plus about 2 feet for the bench and player. If 5 feet is the limit, compare the GB1K and the GCB. With room for 5’3″ or more, the GC1 and C1X are the same length but different series, and worth playing back to back. Our CX series chart covers the larger grands.
