Hey @skyscraper, I found this on the internet. Looks like a pretty good overview of various chinese instruments.
My personal favorite is the erhu, which is a bowed instrument with only 2 strings. It only covers about 2 1/2 octaves, and it kind of resembles the human voice. When it’s played in the hands of experts, it can really induce all kinds of emotions.
I highly recommend this erhu concerto that I found on youtube. This is by far the best rendition of this classic chinese song called the "Butterly Lovers". The leading lady is simply amazing! Butterfly Lovers is a very famous chinese folklore. Think of it as the chinese "Romeo and Juliet".
Do you use Spotify or any music streaming services? There are plenty of chinese instrumental music you can find. There are quite a bit of varieties. It really depends on what you’re looking for. Some are older traditional chinese music, while there are also plenty of contemporary ones played with chinese instruments. I would start with the more traditional ones first. I like both, depending on what I’m in the mood for, especially after listening to too much classic rock like Led Zeppelin. It can be very soothing to me. 😀
Hope this helps.
