I am always happy to have as many singers singing my songs as possible, and so, I encourage transpositions. I feel that my songs can work in any number of ranges, as long as the accompaniment can also work in the new key. Some adjustments might be necessary: for example, a section may sound great on piano in the original key but transposed down a third, it might sound muddy. When the song has an accompaniment other than piano, similar difficulties might arise. Generally, these problems can be solved and I am delighted to assist.
In some instances (see “Living in the Body”), I have provided guidelines for conversion to a different voice type.
