To some, classical music may seem like something of the past, yet many artists have sampled classical music, bringing the music to the present. Yet, the issue remains of where one song ends and another begins. It is always smart to give credit to musicians for inspiring a song. Sampling is the process of taking one snippet of a song and using it to form a new song. Key elements of a song, such as a melody or a beat, can be manipulated to form a new song.
