Bard kiting questions

[Alarria]

Hi, hoping some bards can help me out here!

1- How exactly do you go about swapping your lute for horn, when alternating between Chords and Devon's? I have been doing fine swarming, using the strafing method, but I am obviously missing something. I begin my strafe by holding my left and right mouse to run forward, holding strafe key, hitting enter 2x and then im locked into a sideways strafe if I let go of my mouse. I have to hold both mouse buttons to circle while strafing, and can use hotkeys to switch songs, but my mouse is being used, so how do I swap lute for horn and vice versa?

2- For charm kiting, I've been told that due to how pet aggro works, you can't pull a group and charm 1 and have social aggro get the pet super low and break/dot to death? I'm not level 27 yet, so I haven't been able to test it.

Thank you for any help!
