This is a picture of someone playing a guitar. I chose this picture because it shows how vibrations of string can produce sound. Depending on how fast or slow the guitarist strums and where he decides to press his fingers on the frets, he is able to control the tempo and musical notes of the guitar. This picture also shows how a strum is much like a period of a pendulum. When the guitarist plays short periods, he plays a faster tempo, and vice versa; if the guitarist plays a slower period, he plays a slower tempo. Also, this picture can relate to myself because I enjoy playing guitar too.
