[The Bard Rocks]

Mick, it goes back to my earlier post here. Let's take an example, any song in G. What's the highest note? What a dumb question you may think; it's not the same in every song. Could be a B, a high D, or even an E at the top of the staff. Exactly. Each song is different; it's your voice that doesn't change. It still reaches only so far in either direction, no matter what the key. So the trick is to find a key where your highest and lowest notes are more centered and easier for you to reach. And a capo can make that easier; that's its biggest trick (but not it's only one).

And if one is blessed with a wide vocal range, it can still make a difference as often the timbre, the quality of one's voice changes when you extend your range and with the use of a capo you can keep it sounding like you want.

Or you can learn to finger chords and play scales in all the various keys. That's what everyone should do, only no one wants to, or needs to - if they use a capo.
