It also the famous part of Holsts The Planets, Jupiter 2:54 mark
Hey LIIW,I only listened to the excerpt offered by the OP (not Keypeg's recording offering) andfound it to be Dvorak - for sure. Listened to the Holst - at the mark you suggest - and although in a similar vein (of using the major 6th interval, instead of the leading tone), - it is not the same melodic line. FWIW.
I'm glad that you were able to find (maybe) what Liiw heard (the major 6th). I listened again to the original. It is definitely the Dvorak, without a doubt. Goodness knows I practised it enough for that recital back then. I know the piece.
On a side note, I think it's time to listen to the whole work - Planets. One of my students brought up that piece yesterday, saying she likes to study w it on. So for me, LIIW, your reference is at very least 'Jungian' in its timing.
I just listened to the Holst again. It's not even the same rhythm. While the Dvorak is the same rhythm, the same melody.
Gosh there really must be something like musical blindness. At least you felt the need to repeat yourself again, and again. Maybe again? Sounds like same melody and rhythm to me, maybe slightly slower, perhaps that is why you are so confused.
