What is Air Grab?
1.
to grasp at the air, usually performed by moving your arm upwards abruptly - grabbing at the air - then bringing you arm (slowly) back towards your body.
usually used in combination with slow music (at the beginning of a bar/phrase), or at the climax(es) of a piece, to show the impact certain musical features have apon you.
it is quite hard to describe without seeing one yourself... but it's quite a deep action, you yourself will feel when a musical air grab is necessary. (in your heart or something)
go now, sit down to your favorite track and feel the air grabs come (you should bear in mind that they work much better in slower sort of "emotional" type songs. Not emo, or screamo
etc.) !
