I met with Annette chapman who gave me the best bit of paper I have seen so far in my research. It supplied me with all the answers i needed and generated ideas to get this project up another gear.
I was happy to find some information that gave me an indication of where singers range generally are. In the diagram you can see that C4 which is middle C is roughly the middle of all the ranges for man and woman.
After some thought I have decided that i will base my scales somewhere around G4 and D4. The scales will be able to go right up the octave to D4 hitting D3 in some case all the way down to D5/G5. It will also be important to have a section on the CD that informs the listeners that they should drop out if they feel discomfort and expanding the range should be done over time and with tuition.
