The Yamaha U3 is simply the most respected upright piano in the world, used by conservatories, rehearsal rooms, and professional musicians in over 100 countries. Its 131 cm height provides an acoustic chamber and soundboard 15% larger than the U1, resulting in sound projection and bass depth that rival smaller grand pianos. The Floating Support System—adapted from grand pianos—allows the soundboard to vibrate freely, enriching the tonal palette, especially in the bass and midrange registers. The Acoustibars control and amplify the soundboard vibration. The 5-post solid spruce back frame provides a solid and stable base for the forces exerted by the string system. The keys, longer than most upright pianos, offer a touch closer to that of a grand piano, with greater leverage and dynamic response. Manufactured entirely in Kakegawa, Japan, with seasoned materials for its intended use, the U3 is also available as a SILENT Piano™ and as a TransAcoustic Piano™.
