I'm trying to imagine Lighteyes like Jasnah looking very proper while using a slide whistle...
For stringed instruments, even if you used your freehand to pluck, it would be very hard to press down the strings with your safehand without muting them. If you used a your safehand (and a pick) to pluck then there would probably still be the same problem. (Since a havah, which a proper lighteyes would wear, has very long sleeves)
First post, yay!
