Tubing that is partly interfering with pianos? (4)

Ross

I believe the answer is:

pipe

'tubing' is the definition.
(pipe is a kind of tubing)

I can't explain the remainder of the clue.

(Other definitions for pipe that I've seen before include "Tube for conveying gas or liquid" , "Tube; wind instrument" , "Duct; briar" , "Tobacco is smoked in it" , "Tube to carry water, gas etc" .)

I've seen this clue in The Times.
