Maybe I’m misreading some of the above, but that seems incredibly dismissive of what’s a rather lovely instrument… and I can’t say I’ve seen this argument about it, but it sounds an awful lot like the people at my music school who sneered at the fact that I also played electric bass, or the guitarists and pianists I’ve known who have sneered at the fact that I play synths - and hell, the people who play keys sneering at someone using a sequencer. We should be beyond the belief that an instrument that is easy to play is somehow inferior to one that isn’t, especially here of all places. I hope that isn’t what is being said here. I can see where that would be off putting to someone who is busking with an instrument that isn’t so simple to just pick up and play, but that debate is one that is not remotely unique to any one single instrument.
Anyways.
We have one, my wife picked one up a while back. Yes, it’s a limited scale tonal percussion instrument. It is a quite different sound than the hang drum and the steel drum. Sure, you could probably approximate it with a synth or samples, but show me an instrument you can’t do that with.
From what I can tell, the major “problem” with it is that it’s a fixed scale. It can be very expressive, via making use of harmonics as well as the incredibly dynamic and tactile nature of it. a fixed scale does limit the musical keys you can play in a bit. Some of the rav vast scales, like the RUS, make some interesting compromises to allow for a bit more flexibility.
The attack is as good as you make it. I was playing one through an instruo arbhar earlier and it sounded quite nice - it did not require a complex mic setup. I’ll try to post some tomorrow as I’m off to sleep at the moment - it is definitely a similar friend to electronic music as the kalimba, just much larger and with a sound unlike what I’ve heard in any other instrument… one I much prefer to the hand pan / hang drum.
Tuning should be a non issue due to the tongue design unless you somehow shave off mass or severely deform it.
They are incredible sounding in real life, recording doesn’t do it justice.
It’s impossible to pick one up and make it sound bad, which leads to a lot of the “meditative” use of it. This makes it a god music therapy instrument as well. That isn’t a bad quality, in my opinion.
I’ve definitely seen some really odd stuff like people posing with them in extreme yoga poses - cool if that’s your thing I guess, but I think that may be the sort of thing that has caused some to dismiss it. Put all that aside and what you really have is a truly unique sound in a fun and easy to play package, and I think there’s a lot of potential to work it into electronic music. I plan on experimenting with it more.
The 800-ish USD they go for is quite reasonable for what they are in my opinion- I’ve seen plenty worse instruments at the price point.
