The clanky sounds of cheap bamboo or the high pitched screeching of tiny metal chimes are not pleasant. I have two sets of tuned chimes in my garden that are 1" diameter. They both have 6 chimes that are tuned as a set, but they are also tuned when heard together. One set has longer chimes than the other, so when heard together the chords are much richer.
I know it sounds bougie as hell, but it's really quite a nice effect.
