Songwriting and composition are different fields, though someone could transfer from one to the other. For BM programs, a composer needs a portfolio, preferably with performance(s) by live musicians- sometimes via summer programs. For BA programs, usually no portfolio needed, and some students like the OP’s daughter could get into composition in a liberal arts curriculum.
For VP, Does she want choral, jazz or contemporary/popular? Is a classical foundation something that is needed and desired?
