Bold Battlesinger

When rolling for initiative, you can use your Charisma modifier instead of Dexterity. You have learned to read the battle like a conductor reading a score, using your natural charisma and stage presence to seize the initiative and take control of the battlefield.

You learn how to use your music in the middle of combat to distract or deceive enemies. As a bonus action, which you take after attacking a creature with a melee weapon, you can play a distracting riff using your musical instrument in the middle of the combat. The creature attacked must succeed in a Wisdom saving throw against a Performance check of yours, or the next attack roll made against it until the end of your next turn will have advantage. Creatures that can't hear you, that are immune to being charmed or were affected by this feat in the last hour are immune to this effect. You can use this feature a number of times equal to your proficiency bonus, and all expended uses are regained after finishing a long rest.
