Genius 158

[professorplum13]

Definitions are normal but some of them require a positive to negative switch(or vice versa) before entry in the grid, as indicated in their clue's wordplay. I think the word length may be altered too.

8d Instrument's uplifting tune's beginning, no awful note produced (11)
11a Suspect couple bound to be uncertain, legally (2,5)

[angus]

11 is not in Chambers, nor is the spelling used for 8d

[professorplum13]

Can anyone help please?

[iminoz]

IN DUBIO is a legal term for uncertain, I can't parse it though

[scorpiojo]

ii (couple) + bound

- suspect = anagram?

[Jackdaw33]

I can see Duo.

Jo has it JD, in my opinion anyhow.

If I read the whole question , I'd have seen that was said, sorry.

8d Themed..think Australian instrument

[Jackdaw33]

The only one I can think of has 10 letters so I presume there is an alternative spelling

[scorpiojo]

..it's themed....

Think I have 8dn but what's the wordplay?

[kati15]

Sorry got it - I was trying to parse the answer before making the pos/neg change!
