Tuning Fork, 3 Pack A440Hz Tuning Fork - Standard A 440 Hz Violin Guitar Tuner Musical Instrument with Silicone Hammer

They are very nice tuning forks. When I tested them with my Korg tuner they do indeed come out to be perfectly 440A. If there was one thing I could change about them, I would put a long rubber handle on them so they are easier to hold, but overall I am very satisfied.

I purchased these for a demonstration of sympathetic resonance. Unfortunately they were two small, thus not loud enough, to be useful for a large group demonstration. However, this is not the fault of the company as they list the size correctly. Oh well.

I know how to use a tuning fork as a musician, so I did it right, but these are cheap and useless, if you can get any sound doing it correctly, it is so soft as not to be heard well. Wasted money on this one, was going to use it for a workshop and had to cancel that activity.

Like other reviewers I immediately tested them using a digital tuner. Two are low, 436.0 and 435.8 hz. The other is high, 442.0. I am going to keep them and adjust the pitch using a file, because the tone is strong and clear. The included mallet is useful.Raising the frequency is done by removing material from the ends with a file or sandpaper. I have read that the frequency can be lowered by removing material at the bottom or center where the tines join, but I have not proved that it works.

My daughter wanted these to play with so I can’t really say if they work for anything other than that. They seem to be good quality and weren’t flimsy. I would recommend for anyone that’s is looking for a tuning fork for a kids toy

I very much liked the price point of this product compared to what you get. You get multiple tuning forks, a mallet, and a convenient pouch. I used this for a science fair project involving tuning forks.

Bought for my 3rd grade classroom. Didn't notice that all three forks were the same time. Sad!

Despite their description and the number stamped on the stem, these are NOT 440Hz but measure 435 Hz. Close, but not close enough
