The PSR-E273 from Yamaha is 61-key portable keyboard with almost 400 sounds, 100 accompaniment styles and 102 songs. Lesson guides and Yamaha's Education Suite (Y.E.S.) provide deep resources for practice and education, and with an optional cable, the musical experience can be broadened by connecting to an iPhone, iPad, or iPod.

Built-in amplifiers and speakers, and an Ultra-Wide Stereo processor deliver great stereo sound, while a headphone output provides for private practice or playing. Basic effects enhance the sounds of the instrument, and a dedicated piano button and a damper pedal input (pedal not included) deliver an authentic piano sound.
