Withdrawing my application?

Hi everyone! This is my first time posting so bear with me. I recently applied to UD under the major music composition, and I haven’t submitted any of my music supplementary materials. However, now I realized that I would not like to go here, and would like to withdraw my application . How would I go about doing that? Thanks!

(I haven’t received an admissions decision, my school has yet to send my transcripts, and the school and the music composition professor have already emailed me about receiving my application).

You can just contact the admissions office and state that, or just not submit any more info. Eventually the file will be closed with no more info.
