I just need a hand with the following passage, would like to know what fingering you would use for it. Cheers for any replies!
p p p p p
|-19^15--15-19^15-17^15--15-19^15-17^15--15-| \
|------17--------------17--------------17---|
|-------------------------------------------|
|-------------------------------------------|
|-------------------------------------------|
|-------------------------------------------| p p p p p
|-19^15--15-19^15-17^15--15-19^15-17^15--15-|
|------17--------------17--------------17---|
|-------------------------------------------|
|-------------------------------------------|
|-------------------------------------------|
|-------------------------------------------| p p p p
|-21^17--17-21^17--17-21^17--17-21^17--17-|
|------19--------19--------19--------19---|

pointer for the 15, middle 17 and ring for 19. Kirk uses his pinky for stuff like that instead of his ring finger.
