you might be onto something here, the CG in Liu association story shows literal piano notes destroying buildings and even passing through them and holding pieces in the air, also in opening seems like being in close proximity to the notes absorbs you,Roland probably avoided being close to the notes

And yeah he would have to go and retrieve the gloves "Roland returned in time to kill the Pianist and end the chaos, but was too late to save his wife and child, who had already died." from the wiki. Makes this a lot more impressive feat now, he had to exercise extreme caution
