Guild Wars 2

The idea is a little like the dance manual which requires one player to start it and he/she can invite others to sync with them.
This upcoming Dragon Bash really set’s the mood with that wonderful theme song and it reminded me of how bad I wanted to make some music in this game and how it lacks the emotes from gw1.
The manuals can be bought from the gemstore and each event can have it’s own song or two in it.
When used the owner chooses which song and starts inviting others the same way as the dance manual.
Once started/invited your skillbar changes giving you 4 options:
Flute, violin, guitar, drums (these can change with each manual to match the type of music)
And maybe add an option to clap or stomp to the music.
Players can choose which part of the song they will play based on the type of instrument they choose, but if they please to do so they can all play the drums.
Since they are in sync, they will always play in tune and no hard efforts are needed to play along.
Songs play for 30-60 secs before they loop and everyone can join in whenever they want.
This upcoming event calls for some community music!!
