A bright sounding piano is a type of instrument that has a higher level of treble and clarity. It produces a brighter, more lively sound than traditional pianos. This makes it popular for genres like jazz, rock, and pop music which require an articulate sound with high frequency tones. Bright sounding pianos have been engineered to produce their unique tone by utilizing techniques such as increased string tension or the use of specific materials for parts like the soundboard or strings. Additionally, players can further customize the brightness of a piano's tone by manipulating parameters like hammer hardness and voicing to alter the resonance characteristics of its components.
