I worried about clef/key. Music might be in G major and the treble clef — two very different things. I suppose the clef provides a “key” to what pitches are used, but this is a bit of a stretch, methinks. Is there another explanation?
This was good fun, only alar was new to me. I liked PRIVATISE.
Yes, indeed, breezy good fun from Goliath – just a one-coffee solve! My favourites were LATHE, PARTIES and BIDETS (all for their neat surfaces), FLY-TIP and DELIVERED which, given Goliath’s profession, is particularly smooth.
Thanks Goliath and Oriel.
Puzzle was a joy–thank you Goliath, and thanks to Oriel for a great blog!
Yes GDU, bit of etymological bricolage there — clé, key, clef, register … And ditto alar — vaguely thought hmm .. aileron .. whatev. But yes, smooth fun overall, ta G and O.
It’s good to break my duck for the week.
GDU @1, if you’re not happy with the musical sense, there’s also a roman à clef
Another lovely crossword – that is three in a row now from the FT.
I found this fairly easy, with one or two convoluted clues to pose a challenge. Many ticks: INTRO, I shared LATHE with Diane, FOREIGN, BALONEY, APPARENT, and SUCCOUR. I was happy to see no unsignalled “lift and separate” clue today.
Tell me, what is a FLY TIP, and how is it different to an ordinary tip?
Thanks Goliath and Oriel
A fly tip is an illicit disposal of rubbish often at the side of the road and in the middle of the night. A blight on modern life.
Thanks for an enjoyable puzzle and blog.
Thanks SM@8
Thanks for the blog , very good set of clues as always .
Wot no fission .
