A music arranger, also known as a composer, composes music based on his understanding and application of music theory. The music could be entirely instrumental, or it could include lyrics written by the arranger or from other sources. He could work alone, with a partner, or with a band of musicians.
Because music is used in so many different mediums, a music arranger’s job is often multifaceted. He may be asked to compose or arrange music for live performances or studio recordings. A music arranger is often responsible for the music heard on television and in movies. He may compose music based on his own auditory vision or in response to the desires of the person or company for whom he works.
A music arranger’s creative process is typically very personal. His approach to writing or arranging a musical piece is determined by his personal style as well as the composition’s goals. He can work from handwritten notes or professionally recorded audio. The process can also start with a tune that the arranger hears over and over in his head.
Regardless of the method, the arranger usually identifies the desired effects and then moves on. He chooses the tempos, tone balances, and rhythms that will be used. The voices and instruments are selected, as well as the harmonic structures that will work best.
Some arrangers prefer the traditional method of music composition, which involves writing musical notes on paper to create songs. Other musical arrangers prefer to compose and arrange music using synthesizers and computers. The computerized method allows the arranger to quickly evaluate tunes and arrangements while experimenting with different applications.
Sometimes a music arranger is asked to adapt a previously written piece for a new medium or application. This may necessitate him modifying orchestral or band compositions to suit the needs of a choral group or vocalist. Other frequently requested adaptations include converting a piece written for one instrument, such as a piano, to a format suitable for another instrument, such as a guitar.
Changes in style are occasionally requested. The arranger is frequently asked to rewrite a piece written in a jazz style for a rock format. In order to incorporate these changes, the arranger frequently needs to enlist the help of other arrangers or composers.
This position usually requires years of musical training. He could also be a musician who has worked in a studio or on stage, or he could have a background in music production. Although a music arranger may specialize in one genre, it is common for him to work across a wide range of musical genres and venues.
