April Jam Session and workshop!!

Hi all!! Let's keep the jamming and music learning going!!

If you have definitely no music training before, I could give some technical advices for all instruments mentioned in the group name except harmonica. I could give some singing technique advices as well if you are a singer :)
如果你是從未學過這六種樂器的, 除口琴外我也能夠俾到一D技術性既指導. 如果有需要我也可以俾到D歌唱技巧的意見.
