The brand has established a legacy of crafting exceptionally well-made pianos over the years that have been played by some of the most celebrated musicians in the world, including Dave Brubeck, Liberace, and Nat King Cole.

An Overview of the Distinctive Acrosonic Baldwin Piano

Musicians could attack the keys with jazz-like gusto without compromising nuance and expression.

This winning combination made the Acrosonic a top choice for pianists playing lively rhythmic styles like ragtime, boogie-woogie, rock and roll, and jazz. It became a staple in schools, lounges, churches, and homes across America and beyond.
