A word about harps
One of the best harps is the Lee Oskar harp
which is easy to bend and sounds very loud (a little rough though). For a
smoother sound better take a Hohner harp, which is
all in all not that good in quality, but also cheaper.
Also check out my Linux-Page for some useful (and free!!!) software for musicians. (e.g. guitar-tuner, chord-transscriptor)
