The way to make a soft blow hard (4)
I believe the answer is:
path
'the way' is the definition.
('path' can be a synonym of 'way')
'make a soft blow hard' is the wordplay.
'make' is an anagram indicator.
'soft' becomes 'p' (musical abbreviation for piano, 'soft').
'blow hard' becomes 'th' (I can't explain this - if you can you should believe this answer much more).
'a'+'p'='ap'
'ap' with letters rearranged gives 'pa'.
'pa'+'th'='PATH'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for path that I've seen before include "Established route" , "Line of travel" , "Track, way for walkers" , "Skin on top of head" , "Pavement" .)
