A music arrangement is the second step right after music making. When we have a composition, we need to decide what instruments should be used, how the record should sound in timbre, what should be the rhythmical structure and what format of the composition should be. For example: intro, verse, chorus, culmination, ending. Music arrangements are important to achieve the best sound available. A good music arranger can turn an average composition into a great piece of art by using his professional techniques, intuition and good taste.
