Report text Keyboard Piano (Soal Menentukan Makna Kata)+Jawaban
The piano is a musical instrument which is played by means of a keyboard. Widely used in Western music for solo performances (52), ensemble use, chamber music, and accompaniment, the piano is also very popular as an aid to composing and rehearsal.
Pressing a key on the piano's keyboard causes a felt covered hammer to strike (53) steel strings. The hammers rebound, allowing the strings to continue vibrating at their resonant (54) frequency. These vibrations are transmitted through a bridge to a sounding board that couples the acoustic energy to the air so that it can be heard as sound.
