Music ticket is an item you can get from performing and doing performance related quests. It currently has no use, and it cannot be sold. If given to pets, it can be sold - see below. The amount of tickets given at the end of a performance quest seems to be related to your final score. (i.e; 593 passing score rewards usually 59-60 tickets.)
When given to your allies, the music tickets cannot be reclaimed and are eventually sold for gold, much like Ore or Small Medals. When sold this way, they bring 1gp per ticket - a tenth of what a junk stone brings. So don't give them to allies; it's not like they're heavy.
In Elona+, you can trade Music tickets with rich person <Stoke> in Arcbelc for rare foods, diaries, and precious items. Moreover, Music tickets can now be obtained in dungeons during Nefia fever mode.
