How should I tune a 15 string harp?

Question:I just bought a 15 string lap harp and I was wondering how should I tune it? I thought about tuning it every semi and whole note starting at C up to the D an octave above the first C so I can play in any key, but I end up getting a very limited range.

As well, if you can, please recommend any websites that have free sheet music, thanks.

I don't play harp but I know some people who do.

You tune it to a C major diatonic scale -- the red strings are C's and the blue strings are F's. Better quality/more advanced models have sharping levers on the C and F strings to facilitate retuning to play in different keys (want to play in G? Flip the sharping levers on all the F strings to make them into F#'s -- no problem). Top quality harps have sharping levers on every string to make the instrument fully chromatic. If your instrument doesn't have sharping levers, then to play in different keys, you'll have to manually retune to get the necessary sharps or flats you'll need for the key you want.

Hope this helps.
