Musicianship

Summary

A player's effective barding skill in Discordance, Peacemaking, and Provocation is capped by their Musicianship skill

A player cannot receive more bonuses to their Effective Barding Skill higher than their Musicianship skill (i.e. at player at 25 Musicianship could only gain 25 Effective Barding skill from Instruments, Supplemental Skill Bonuses, Lyric Aspect Armor, etc)
A player's Effective Barding Skill is (Base Barding Skill + Instrument Skill Bonuses + Instrument Slayer Bonuses + Skill Slayer Bonuses + Lyric Aspect Armor Bonus)
A player's Base Barding Skill is capped by their Musicianship skill (i.e. 50 Provocation and 25 Musicianship = 25 Provocation)
A player total skill bonuses received from Instruments, Lyric Aspect Armor, or Slayer Bonuses is capped by than their Musicianship skill (i.e a player with +50 total Barding skill from their Instruments, Lyric Aspect Armor, and Slayer Bonuses, but who only has 25 Musicianship skill will only gain +25 Barding skill from them)
Barding Success Chance = (Effective Barding Skill / 100%) - (CreatureDifficultyValue * 1.0%) See important examples in patch April 7,2020
A player's Minimum barding success chance is now ((Effective Barding Skill / 100) * .25)) See important examples in patch April 7,2020
Any creature of 150 Difficulty Value or higher (such as Spectral Terrors, Elder Vampires, etc) will now receive Boss Barding effects instead of being Pacified or Provoked
Boss Barding effects reduce the Melee Attack Speed and Casting Speed of the creature by 25% and increase delay of Ability Cooldowns of the creature by 25%

Players have the ability when using Barding skills to target the ground and activate a Barding Song
When a player activates a Barding Song, the effects will now only be granted to themselves and any other players or creatures who flag as Green to them, or are in the same party as them
In order for a player to benefit from a Barding Song (Song of Provocation/Peacemaking/Discordance) the player be within 50 tiles of the player who created the bonus (if multiple people activate barding songs near players, it will always use the highest valued version of any player within 50 tiles)
A player's Barding skill for determining song effectiveness is capped by their Musicianship skill (i.e. 70 Musicianship and 90 Provocation = effective 70 Provocation)
Casting a Barding Song has a 10 second cooldown that is independent of normal bard skill usage

The Barding Songs are:

Song of Provocation: Increases Damage Dealt by (5% * (Provocation / 100)) to creatures
Song of Discordance: Reduces Damage Taken by (10% * (Discordance / 100)) from creatures
Song of Peacemaking: Increases Melee Accuracy and Charged Spell Chance by (5% * (Peacemaking / 100)) against creatures

The Barding Song Durations are: patch April 7 2020

Barding AoE Song Buffs durations have been extended to 15 minutes (previously was 5 minutes) Patch Notes 20191003

While a non-Boss creature is Provoked or Pacified, for every 1 second that passes there is a ((CreatureDifficulty / 100) * 1%) chance they will suffer a "Barding Break" effect that will last for (CreatureDifficulty / 10) seconds

When a creature suffers a Barding Break:

A "Barding Break" message will appear over their head and a sound effect will play
Their Provocation and Peacemaking effects (but not Discordance) will immediately end
They will have Provocation and Peacemaking immunity while the Barding Break is in place
The creature will suffer -50% Attack Speed, -50% Casting Speed, and +50% delays between Abilities while the Barding Break is in place (i.e. the same effects concept referred to previously as a Boss Barding Effect)
