Bards who enter this college typically do so on their own time.  They will purchase the tomes needed and decipher them on their own, consulting experts only when needed.  Once their training is completed, these bards can create lifelike duplicates of themselves to aid in their performances.  These duplicates rival those created by clerics and even the strongest illusionist wizards.  

One Man Band

Starting at 3rd level, as an action, you can create an illusionary copy of yourself. This copy is considered an object, and remains summoned for one hour, until you fall unconscious, it is more than 120 feet away from you, or until it drops to 0 hit points wherein it bursts into a small shower of harmless multicolored sparks.  The copy can also be dispelled via a dispel magic spell.  As an action, you can see through a copy's eyes and hear what it hears until the start of your next turn. During this time, you are deaf and blind with regard to your own senses.  You can communicate telepathically with your copy and it has a quasi physical form that can interact with everything around it as a creature could. 

The copy is summoned with an instrument and weapon of your choice on its person that you are also proficient with and have on your person.  A creature must use its action to examine the copy before it can determine if it is real with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusions for what they are, the illusions become faint to the creature.

The copy acts and speaks independently of you but always obeys your commands and in combat it acts on your initiative, but immediately after your turn.  The copy's ability scores, movement speed, and proficiencies are identical to your own.  It has an AC equal to 10 + its Dexterity modifier and a number of hit points equal to your proficiency bonus plus your Bard level. On its turn, it can take any action as a normal creature could, but can only make attacks with the weapon it appeared with.  Additionally, when both you and your illusion are within 5 feet of a creature that can see, you and the illusion gain advantage on attack rolls against that creature.

You can summon an additional copy at 9th and 18th level.  Once you use this feature, you can’t use it again until you finish a long rest or expend a spell slot of 2nd-level or higher and one bardic inspiration die.  The maximum number of copies you can have at once is equal to the number of copies you can summon at a single time.  If you try to summon more copies than your maximum, the oldest copies will burst into sparks until you are at your maximum number of copies.

Play in Unison

Starting at 3rd level, you gain proficiency in an instrument and simple or martial weapon of your choice.  You also gain advantage on Charisma (Performance) checks while playing music with your copies.

Duplicitous Magic

Starting at 6th level you learn how to transfer some of your magic into one of your copies.  As a bonus action you can expend a Bardic Inspiration die to allow one of your copies to cast a cantrip that you know with its Action.  If this cantrip deals damage, roll the Bardic Inspiration die, and add the total to the damage roll.  If this cantrip does not deal damage, it instead gains temporary hit points equal to a roll of your Bardic Inspiration die.

Psychedelic Finale

Starting at 14th level, you gain the ability explode and destroy all your copies in a musical explosion.  As an action you can explode all of your illusory copies in a psychedelic finale, forcing each creature within ten feet of an illusory copy to take 4d8 psychic damage.  A creature in the area of more than one musical explosion is affected only once.  Creatures that take this damage must also make a Wisdom saving throw against your bard spell save DC or be stunned until the end of your next turn, in awe of the beautiful finale.

In addition, when you cast a Bard spell with a range of self and does not deal damage to another creature, all of your copies also benefit from the effects of the spell.
