arrange some music for

1. To organize or plan something. A noun or pronoun is sometimes used between "arrange" and "for," and a specific time is often given after "for." I will arrange for you two to meet this week. I need you to arrange a luncheon for the whole department. Carrie asked me to arrange a conference call for 10 AM.

2. To adapt a piece of music so that it can be played on different instruments or in a different style than is customary. A noun or pronoun can be used between "arrange" and "for" to indicate the piece of music. I would really like that piece to be played at our wedding—can you arrange it for strings? That song was arranged for the piano by our musical director. This song isn't really arranged for trumpet, so I'm worried that it will sound bizarre.
