Wind instrument half-opens chord and beat limits? (9)
I believe the answer is:
alpenhorn
'wind instrument half-opens' is the definition.
I can't judge whether this definition defines the answer.
'chord and beat limits?' is the wordplay.
'chord' becomes 'E' (E chord in music).
'and' becomes 'n' (common abbreviation for 'and').
'beat' becomes 'alphorn' (I can't justify this - if you can you should believe this answer much more).
'limits?' indicates putting letters inside (limit can mean to contain or block off).
'e'+'n'='en'
'en' placed into 'alphorn' is 'ALPENHORN'.
Can you help me to learn more?
(Other definitions for alpenhorn that I've seen before include "Swiss wind instrument" , "blown up" , "It's a blast" , "Instrument for communication" , "What plays (over the heads of many)" .)
