There are two schools of thought in regards to how your rock guitar, bass or keytar is slung. The first school says that to be as cool as possible, the guitar should be slung as low as possible while the musician is still able to play the instrument.
Generally the maximum low is roughly when the guitar body is as low as your groin and the rest of the instrument appears as if it is coming out of your groin area. If you think I am saying groin a lot, you would be right.
The guitarist, bassist or keytarist plays with this giant instrument that is coming out of their groin. Isn’t that cool? Or is it just masturbation?
One might wish to call the guitarist, bassist or keytarist a giant dick. But they will just respond with a simple, “I’m not a giant dick. I play a giant dick.”
The other school of thought around guitar slinging is that the guitar should be held up high enough that the musician can play with maximum agility, speed and stretch. This musician can now play more complex pieces if he/she wants to.
It’s no surprise that the prog rock guitarists, bassists and keytarists all seem to play with their instrument up higher, more like the body of their instrument is based at the belly button and the instrument appears to come out of this area. Not only do prog rock musicians do this, but, virtuoso musicians like Eddie Van Halen and Mark Knoppfler also do this.
Not only is this much better for the complexity of the music, you can even say Steve Howe (of Yes) is such a good guitarist that he practically came out of the womb playing the umbilical cord. Yup, straight out of the belly button. No wonder virtuoso musicians play from the belly button.
