Do you have absolute pitch? What is your hand span?
Do I have absolute pitch? No. There are many times I wish I had perfect pitch; it would certainly make the process of composing much easier. Instead I have the much more common form of relative pitch.
What is my hand span? I can comfortably reach a tenth. If I approach the keys really slowly (stress: really slowly), I can reach an eleventh. Sometimes I wish my hands were smaller; it would make it easier to perform Mozart's music, but the large reach is useful for late-Romantic music and contemporary music.
