The Yamaha P-45 Digital Piano pairs an authentic playing experience with an accessible price tag for an easy avenue to big tone in a compact package. Built with 88 Graded Hammer Standard (GHS) keys that emulate the nuance of an acoustic piano, the P-45's secret weapon is the Advanced Wave Memory (AVM) and 64-note polyphony to serve the iconic sounds of Yamaha's flagship grand and baby grand models. Clocking in a 25 pounds and sleek in design, this go-anywhere model is an apartment dweller's best friend.
