Battle Muse
At 3rd level, a Maestro gains an additional use of Bardic Inspiration. They gain another additional use use at 6th level, and again at 14th level.

Symphony of Conflict
Also at level 3 learns two Conducting Techniques, which require a free hand, a baton, or wand in order to use. The targets of a Conducting Technique must be able to hear the Maestro, who likewise must be able to see the target.

The Maestro learns one additional Conducting Technique at level 6 and again at level 14. Whenever they learn a new Technique, they can also replace one that they know with a different one.

Frenetic Crescendo
At 6th level, a Maestro can harness the beat of battle and use their action to expend as many uses of Bardic Inspiration as they like and grant a Bardic Insipration die to an equal number of creatures within 60 feet that they can see, other than themself. Once this action is used, the Maestro must finish a long rest before they can do so again.

Virtuoso of Captivation
At 14th level a Maestro can use an action to conduct a mystical symphony, distracting nearby creatures. For up to 10 minutes, using their action on each turn, creatures of the Maestro's choice within 60 feet who can hear them have disadvantage on saving throws against being charmed and magically put to sleep, as well as disadvantage on sight and sound based Perception checks to detect targets other than the Maestro. Once this feature is used, the Maestro must finish a short or long rest before they can use it again.

 * Crash (Marcato): When another creature within 60 feet hits with an attack, the bard can use their reaction to expend and roll a Bardic Inspiration die. The attacked creature must make a Strength save or take thunder damage equal to half the roll and be knocked prone.
 * Dirge of Dread (Finale): When an ally of the bard reduces an enemy within 60 feet to 0 hit points, the bard can use their reaction to expend and roll a Bardic Inspiration die.
