Yamaha GC1TA2 TransAcoustic

It starts with over 12,000 parts, fashioned from the finest aged woods and the world’s most advanced materials. Each piece is assembled by artisans in a tradition of old world craftsmanship. When it all comes together, and you touch the perfectly balanced keys and hear the rich harmonics and subtle, silky colors, you know it’s not just any grand piano. It’s a Yamaha.

These aren’t just baby grands. They’re our babies. Yamaha designers, engineers and craftsmen were challenged to bring out the expressive tone, subtle colors and dynamics of a conservatory grand from a more compact instrument. The GB1K and GC Series put the unmistakable sound of a Yamaha grand piano in more places, and in reach of more people, than ever before.




Yamaha TransAcoustic is unlike any piano you’ve ever heard. A true acoustic piano that uses its soundboard to naturally amplify digital sounds, turning your instrument into the world’s most incredible acoustic speaker. Transform your acoustic piano into a Yamaha or Bösendorfer concert grand, an electric piano, harpsichord, organ and more. Then record a track and play along on your acoustic piano. TransAcoustic stretches the imagination and opens up a new world of possibilities.
