Mine was from my Auntie.
She was a singer with the Philharmonia Chorus, and her day job was teaching Maths and Science.
I had the opportunity to buy a 1930 Broadwood upright piano in great physical condition, at what seemed a reasonable price, and although I'd played as an 11 year-old, I knew nowt about pianos or what to look for.
As my Auntie played a Steinway upright in her home, ( the whole family were musical, her husband playing trombone in the Royal Phil), and, I presumed, would have a bit of technical insight as to what to look for as she was into Maths and Science, she seemed the ideal person to ask for advice on what to look for in a prospective piano purchase.
All she said to me was "Just if it speaks to you son, just if it speaks to you."
Best advice I've ever had about anything. It applies to just about every decision I've ever had to make.
.....especially guitars!
If they dont speak to me, I let them be, as they'll speak to someone else.
Cheers,
Colin
BTW, I bought the piano.
