Really bad example for kids to learn using saw. Can't believe he hasn't lost a finger or hand yet. Slight distraction & it's over. My woodworking school would be all over him for doing that.
Hi David, Might you know of an ultra-advanced method for node-finding, like a fancy camera that detects/shows vibration-imagining? Might you know how the big boys do it? I can’t imagine the Marimba One and Yamaha guys doing the salt trick for all their thousands of bars. 🙂
Hi, I do not know of a high tech alternative to the salt. Not sure how Yamaha, for example, does node finding but on their web site it says that bar tuning, and matching, are done by human hand. They also mention that wood is a natural product and each bar has its own character detail and thus they need to manually match the set of bars for each individual instrument. They do not mention how they do node finding. I suspect node finding could be "automated" and maybe with an optical approach - sounds like a good student (high school or graduate school) project.
Could you please do a more detailed INSTRUCTION video? While it was wonderful watching you make it, you didn’t give near enough instructions or dimensions or material lists for someone to be able to duplicate this
Hi Luis, No, all the bars are, more or less, different shapes, varies with the note/length of bar and tonal qualities (grain? and other things?) of the individual bar piece. Look at this page, for example summary of bar tuning: www.yamaha.com/en/musical_instrument_guide/marimba/manufacturing/manufacturing002.html hope this helps.
@@davidaadler The fourth harmonic two octaves above the fundamental sounds the strongest a quarter way from the end. The pitch of the fundamental is lowered by removing wood from the thinner center part of the tone plate. How is the pitch of the fourth harmonic lowered or raised in relation to the fundamental? For instance, does the pitch of the fourth harmonic fall relatively more when wood is removed closer to the quarter-from-the-end point (widening the notch) as compared to deepening the notch, or is the trick something else altogether?
Hi Aaron, the song is Nyungwe by Dumisani “Dumi” Maraire, the story I heard is that Dumi was inspired by the rhythms he heard arriving at a port in Mozambique, the local musicians playing on the dock.
That old guy has no fear of a rotating blade!
For real! He definitely made me cringe!!

It is not indigenous to Zimbabwe. It was introduced in Zimbabwe as recently as 1964. I like your design.
Actually, it did originate from Zimbabwe for this design, but not for the standard marimba with sharps
Really cool video, i really enjoyed it, but as a percussionist, sad to see no accidentals 😢. Not F#.
Is it possible to get the dimensions of the keys that were on the chart in your video? I really enjoyed this!

Excellent job! I was wondering if we could have those sizes annotations and structure building plans, given or bought
Pretty awesome, but it looks like you had your elderly friends do the heavy lifting in construction.
The experienced teach the young.

Did you tune the bars BEFORE drilling holes through them?
But - nice instrument!
PVC pipe for resonator tubes?
Is the inner cut always same size? the arc under what size

Does Anyone know the name of the song that is playing in the background between 13:00 and 14:00
