Overblow

[MCCREA50%snypotva.BITNET@xxxxxxxxxxxxxxxxxxx]

OK, I know why overblows work and how beneficial they are in you playing.  Can
anyone post some useful information on exactly how to work on it.  I still
can't get it to work.  Am I right in understanding that an overblow should
raise the pitch?  I'm trying all kinds of harps (star performers, marine bands,
spec. 20's lee oskars and golden melodies.)  your help would be greatly
appreciated.
