The YDP-135R has an excellent entry-level piano action with graded keys that have a heavier touch in the low end and a lighter touch in the high end. This conveys your subtle playing nuance with authentic comfort. AWM Stereo Sampling creates a high-quality, spacious, stereo grand piano sound. The built-in, 1-track performance memory allows you to record a single performance and play it back instantly, ideal for either review or to play along with. There's also a built-in metronome to help you stay in perfect time. The built-in soft, sostenuto and damper pedals complete the piano playing experience. 50 classic piano songs are provided in the song player and as a music book, "50 Greats for the Piano." These songs can be used for background music or as learning reference. Attractive wood cabinetry and Yamaha's legendary heritage in piano craftsmanship make ARIUS/YDP the premier name in entry-level console digital pianos. The simple and elegant design fits into a wide range of decor and living spaces. Includes "50 greats for the Piano" songbook and BC-100 standard bench.
