The sampling in music is fairly a new concept which has been introduced recently. Here sampling is the act of taking a portion of one sound recording and reusing it as an instrument or element of a new recording. This type of sampling is possible with tape loops or with vinyl records on a phonograph. Over sometime, sampling has become a major part of making modern music.
Everything from break beats, loops, world instruments, vocal performances, chants, even industrial sounds have all found their way into the music of the last two decades. Sampling has changed the way the music was made. The samples are collected from the musical instruments by the workstations and samplers and they play a sample back at any pitch on their own. Many modern synthesizers and drum machines also use samples as the basis of their sounds.
These are usually developed by the manufacturer of the instrument or by a subcontractor who specializes in creating such samples. There are businesses and individuals who create libraries of samples of musical instruments. Of course, a sampler allows anyone to create such samples. This introduction of sampling has lead to many court cases as it has lead to violation of copyright laws. Under the newly started CC licenses in the west, remixing and sampling amounts to transforming the music, so you can’t legally remix or sample a song under a CC license.
The need for fresh exciting samples has given way to an industry unto itself and many artists and producers regard their sample library as an integral part of their sound. Several celebrities have even released their own sampling CDs or CD ROMs.
