Скачать или смотреть Aluminum Bar Glockenspiel Tuning (Repair) Making A5 Into A#5

I purchased this Glockenspiel for my son to practice with for his high school music class. 5 bars were out of tune. The manufacture basically said to keep it and refunded us. I chose to order some aluminum stock and teach myself how to make and tune new bars. This video just shows the frequency changes, what you don't see is me removing stock from the ends with a file to bring it into tune. I was hitting G#5 for a reference on the frequency meter. This particular bar came tuned closer to A5 at 858hz instead of A#5 which is 932hz. I am happy with getting it to 934hz. I found removing approximately 1mm from the bar increased the frequency by approximately 25hz but increased to near 40hz as I moved to the smaller bars. Very fine adjustments were needed when getting close to the actual frequency.

This frequency chart was used for reference in tuning:
