Instruments is the most importent thing in music besides voice. Why?, because without instruments we can hear music. Of course we can sing it. But besides singing, there is many thing we can do in music world. There many kinds of instruments. There is stringed instrument, blowed instrument, and much more. I like guitar, but there is the other of course. Such piano, biola, bass, drum, many more. Piano is the classical instruments that very useful. If tuning keys in guitar is turned, we can hear the right tone in piano. Also, Piano can produce the beautiful sounds if we can play it. And guitar!, wow. I like it!. Maybe the other it's so, but i just want to say, Guitar is the interesting and joyful instruments!. I have talk about guitar in my other post (Playing guitar).
