If you like jazz - but it depends which styles, of course, jazz is almost as diverse as classical - then the Jacques Loussier takes on Bach form one bridge. Bit like marmite - love it or loathe it (I hate it
), but as a serious classical musician who puts Bach right at the top, I love JL as well. The essence of Bach is still there but you have the jazzy rhythms and improvisatory feel as well. Ironic really - or appropriate - as Bach was a great improvisor.
As far as classical music is concerned generally, it depends what in music that you like now grabs you: rhythm, melody, power, intimacy, simplicity, complexity, instrumental, voice etc. "Approachable" music is not always so and vice versa. I remember introducing someone with relatively little exposure to music to the late Beethoven quartets, which I was struggling with then. He lapped it up immediately - then I found out he liked Bartok. So I was coming to terms with late Beethoven from Mozart etc and he was coming back from more modern and complex music. (I still can't take Bartok, my world ends around Elgar and Rachmaninoff, with some exceptions) I am happy with my limited tastes
.
There are so many 'oughts' in classical music: eg I ought to like Mozart more than Haydn. Well, yes, I do, but I love Haydn too and there are things Haydn does that Mozart doesn't. He has a different sense of humour for a start.
Classical music lovers have a reputation for being po faced and serious. Yes, great music can put us in touch with aspects of life that nothing else can, but it aint much use if we don't
enjoy it, whether playing or listening.
