Answer:
...piano
Step-by-step explanation:
One keyboard instrument that is often used to play a solo melody all by itself is called a piano. The piano has 88 keys which are arranged in a pattern of black and white keys. When a person presses a key, a small hammer inside the piano hits a string, making a sound. The harder the key is pressed, the louder the sound will be. The piano can play soft, gentle melodies or loud, powerful ones, making it a versatile and popular instrument in many different types of music.
