Grand piano
Used in concert halls; horizontal string layout and large soundboard deliver rich tone and dynamic range. Sizes vary from baby grands to concert grands.
Upright piano
Vertical string layout saves space; common in homes, schools, and practice rooms. Offers good tone for its size and is more affordable than most grands.
Digital & hybrid pianos
Use sampled or modeled sounds and require no tuning. Great for small spaces, silent practice with headphones, and modern studio work. Hybrids combine acoustic actions with digital sound engines.
