VHDL Noob - creating one octave monophonic synthesizer

I am working on a project for school and was wondering how do you go about creating a sound frequency in VHDL? I am using quartus II

I made a synthesizer much like you're a trying to do. I used a PIC micro to read a 24 touch switches and send a byte to the FPGA and it generates a sinusoidal waveform ( with the proper frequency ) during 300ms. I make a ROM table with the senoidal values. This table is read with the DDS method ( phase addition ) and the music note determines the frequency of the waveform.
