Hi, @Musicman99. If you have two days that work for you, I think that is a good target to try to hit two posts a week. If you do this every week, that's 52 posts per hashtag, so 104 posts a year just for that music. As far as promoting on Steemit, you can try the hashtag #openmic and also post on @dlive and @dsound (and also use the categories for #dsound and #dlive).

I've seen at least one Discord group for musicians. I don't remember what it's called, but if you use the #openmic tag in search, you'll probably see it listed in the comments there.

Just like the rest of Steemit, voting and commenting also help. If you are comfortable sharing on Facebook, there are three Steemit musician groups on Facebook that can also be a good way to promote. Good luck, and let me know how it goes!
