## Long description

The Yamaha P-45 is a compact 88-key digital piano with GHS weighted action that reproduces the heavier touch in the low register and lighter touch in the high register, similar to an acoustic piano. It uses Yamaha's AWM Stereo Sampling sound engine to deliver realistic piano tones and includes a matte finish on the black keys for improved grip. The instrument is slim (depth under 12 inches), lightweight (about 25 lbs) and can be powered by a 12V DC adapter; it also offers headphone output for private practice and adjustable tuning between 414.8–446.8 Hz.
Advantages
The GHS (Graded Hammer Standard) weighted keyboard helps build proper finger technique for acoustic piano playing by providing graduated key resistance. AWM (Advanced Wave Memory) Stereo Sampling creates a richer, more spatial piano sound using recorded waveforms. The P-45's compact, lightweight design improves portability and space efficiency, and single-button operation simplifies voice selection, metronome and other functions. An adjustable auto power-off feature conserves energy when the instrument is idle.
Suitable for
Beginners learning piano technique and posture
Home practice where space is limited
Private practice using headphones
Small performances or mobile gigs requiring a portable 88-key stage piano
