This is really hard, as there are lots of those moments! So, what do I choose?
The first time I heard the Ode to Joy from Beethoven's 9th Symphony made a huge impact and marked the beginning of a passion for music. I was about seven years old and as a consequence asked for the LP for Christmas - sad child! I didn't know where the Ode to Joy came in the music - it's near the beginning of a long final movement - and so the family had to endure the whole symphony to make sure the wrong piece hadn't been purchased! Even now, when I hear the melody introduced in the subterranean depths of the string section, and then joined with a counter-melody played by the bassoon, it has the same effect.
The most recent moment is Mahler's 10th Symphony, the Finale. I blogged on this recently, and received a delightful comment. Since then I've been ambused again and again as I've listened to this sublime music.
On a Sunday, driving home from preaching at one of the CBA's 150 or so churches, I listen to Private Passions, a brilliant programme. It's a sort of Desert Island Discs, but with much more conversation around the music. There have been a number of occasions when music has had the 'stand still in wonder' effect, which is a bit disconcerting when you're driving!
One piece was Miles Davis, Time after Time, taken from 'Live Around The World'. The guest introducing this, spoke about how Miles takes the tune and breaks your heart in one way, and then in another, and yet another. And listening to it for the first time, it's just as he said. There's a wonderful moment when Miles plays without his signature Harmon mute and wallops a seriously high note, and the silence that follows makes you stop breathing.
There was a period in our lives when Cazz and I would listen to Late Junction on Radio 3 introduced by the gorgeous-voiced Verity Sharp. Right at the end of the programme, in the early hours of the morning, we heard a version of 'The Air That I Breathe' by The Hollies, played by the virtuoso violinist Victoria Mullova, accompanied by the jazz pianist Julian Joseph and the fantastic percussionist Paul Clarvis. We subsequently bought the CD, 'Through The Looking Glass'. What a great song!
We attended a concert at The Stables with the guitarist Martin Taylor in which he spoke of a recent tragedy in his own life. He played his own take of a tune that had become very special to him and wife, The Londonderry Air. It was one of those occasions when time took on another dimension.
I could talke about the slow movement of Mozart's Clarinet Concerto, Jan Gabarek, Officium, and others.
But finally, I recently came across a video clip on You Tube of a friend from years ago, Dermot Crehan. Dermot is a superb classical vioinist who also is a hugely respected Irish fiddler. He was the solo violinist on the soundtrack of 'Lord of the Rings', and on this clip performs 'Were You At The Rock?'. He's accompanied at one point by another friend, Andy Findon, playing Irish flute. It's a moment of understated wonder.
