More bend notations
i don't know what they are called exactly, please see the attached png (sorry for my drawing skills :/ ).
The first one is a kind of short glissando from an undefined high note down to the note it is attached to. This is sometimes used in jazz trumpet/trombone parts.
The second one is pretty much the other way round, sliding up to the written note from something lower. I think this one can be played on a lot of instruments (strings, guitars, etc)
