Strange sounds called ‘woofs’.

I just read the post of Janic again…and it is also very important what he is writing.
Thank you for pointing that one.

++If it occurs at only specific locations, it might be more of an ambient sonic issue, which is still a real pain.++

Because every hollow body even kitchen, musicroom, harpbodys even landscape have all there own wolf and special resonance places.

Bernhard, I agree… it seems that every room and every container has one or more such things, which I like to call “resonant frequency” (a term I picked up from physics).

I actually have experienced this phenomenon myself –

I had just gotten a new electric guitar ( nice Rickenbacker, actually) and noticed a very, disconcerting warbling in the upper registers. I took the guitar apart, changed strings, changed amps, etc. etc. for a few days on end. I nealy retuned the guita because I couldn;t figure out why it was behaving poorly.

It turned out that the source of the warble was the ceiling fan in my livingroom 🙁

The light fixtures in most of the practice rooms at my school (which might as well all be one big room, since there’s no soundproofing) all seem to vibrate on B or A. Makes playing in a woodwind quintet no fun for the bassoon and horn. I think this summer I’ll make a habit of taking the harp downstairs out of the practice room into a place where it can really sound like a harp.

I’ve noticed one thing, though I’m sure it’s not a wolf sound, but on our Salvi Iris, when I play the lowest E string, it buzzes like crazy (even when I play softly) unless I pluck it extremely carefully. This doesn’t happen on our other harps (LH 17 and 23). Is the string too old, or am I just playing it wrong? And also, if I want to play a really loud octave in the bass, how do I keep from getting the false string effect? It seems to happen when I play a low octave with a flat hand, 3 & 4 on the lower octave string and thumb on the upper note and try to play ff. Maybe I should just be more delicate? I want the loudest, most resonant sound say, on lowest two G’s. Should I play it normally with 1 and 4 open, or as I did before, with flat hand and two fingers on the lower note? Thanks (and sorry for being a little off topic).

Ah, yes – resonant frequencies and interrupted sound waves – I ran into this a couple weeks ago doing some hospice playing in a home – I was set up under a rather low ceiling fan in the lady’s bedroom -running at a medium low speed –

[unknown-user]

John, which striings were affected when the harp was in a corner?

[unknown-user]

the low and mid range felt like it was booming out the most – the effect thinned out somewhat in the top range –
