>>>Ott, if you have a story behind this tip I'd love to hear it!<<<
Alex, now you make me revisit my youth again.
Kids and adults in Germany and Austria love to sing. The many ,many songs are all known by everyone and sung while hiking, around campfires and in the pubs and get-togethers From Vienna to Bavaria and all over.
When skiing with Sigi and our crowd as youngsters, Sigi would often start a song which set the tempo of the turns and then changing it to another which changed the tempo of the turns again.
There is a threefold benefit fo singing while skiing. The first, as mentioned above, is to set the tempo of your turns. It's like dancing. Dancing to a a slow waltz and a fast jitterbug requires differently paced steps. So it is with skiing, while you sing "Somewhere my love, or Lara's theme" from Dr. Zhivago, you are going to flow smoothly in medium turns, while if you sing "In the mood" you are going to do short swings. Though while I often don't know the words to the songs I sing, la-la-la-la does it
Second, while you sing you can't be fretting over technique, you just ski.
And third, very important, as John said, you are breathing...thirty years ago we had a local slalom racer whom we called "Old locomotive" because he was huffing and puffing all the way down the course and he would usually win. Grunting is what the new breed of tennis stars do now. It is important to exhale forcefully, inhaling comes automatically.
If you stood close to the course you could hear that he actually was talking to himself :" OK, oh sh*t, all right, jee whizz, come on, right now, etc." on every turn.It kept his rythm up and kept him breathing.
More than you wanted to know, I'm sure
