I have a vocal range of B2 to E5, but I can’t sing an E5. Okay that sounds silly. Let me clarify. I can produce an E5, just as an ah or ooh sound. I can produce it towards the end of the last word in a line, or as a singular instance in any word in a line. But I can’t sustain an E5 throughout the entire line or verse. So does this note count as part of my range? If so does it have a special name, or some such thing?
