Kalto, which follower are you using, and does this particular follower play with you on any of the other songs?

I use Derekeethus, he dont seem to play any other songs.

Is he currently your temporary follower (for that quest)? Or is this after the quest? Thanks.

I hate when my follower is shy, usually happens when I most need 'em

He's not temporary, I've completed this quest years ago. Im gonna check if other followers will play with me, but Derekeethus is still my favourite : <

Lydia plays the drum just fine but Darekeethus still resists : <

Thanks, Kaito. That will help me narrow down the cause.

don't worry you need to get used to his comfort zone!

I am sure you all got comfy with it... I am using Fallower Tweak, that sends the fallowers into a "sandbox" mode, something about them relaxing and doing their own thing, I have times where they start to play an instrument, then stop within a few seconds... It very well could be a mod you have installed changing the behavior of a fallower...

Marcurio (Located In One Of The Taverns In Riften) refuses to "Jam Out" with me.

I have been given assignment to play for Jarls and it has been working fine until Mavis Blackbriar. The quest comes up with ID arrow over her head,but when I speak to her, she does not recognize me as the Bard like the other Jarls have. She just talks about herself. So I cannot complete the quest.

There is an issue with jarls that have switched from the civil war quests. Best thing to do is simply drop the quest with Viarmo and pick up another one.

ok, Thanks :)

Agmaer from Dawnguard won't play with me, and I gave him the lute, drum, and flute.

none of the followers I grab wanna join in and jam with me. I carry around an extra drum, flute and lute for the sole purpose of having an impromptu band at my beck and call (and I have skyui and stuff loaded up as well, and the option to have followers join toggled) but they just stand there and stare at me like I'm about as interesting as the chair sitting to their left. aside from the three audio mods Wilds, Civilization and Dungeons as well as the DLC Hearthfire, Dragonborn and Dawnguard, this is the only mod I have installed so I doubt the issue is compatability. NPCs also are just about as responsive as my pack mules- I mean followers. Thanks for the help!
