Hey, I`m fairly new to the trombone, so if anyone could help me out that would be great. I`m having troubles figuring out this chart, if anyone as a better one, or can explain it that`d be awesome. thanks

Am also new to trombone. I had trouble finding where the slide positions should be as well. Time and practice helped. Especially using scales. Position charts are somewhat common on the net, such as http://www.ithaca.edu/troupe/reference/positions1.php
Try this one- http://www.tsmp.org/band/scott/scott6.html

Hope this helps.
