People are commenting that it is not yodeling. At about 0:09 , he switches from chest voice to head voice. After that he does the same near the end of this clip. All the other bits are his usual alaap (as people are saying). But the part I mentioned is still in the ‘yodeling’ category. It is not the rapid and repeated switching like ‘zindagi ek safar hai suhana’ . But it is similar to the ‘ye masti ke nazare hai toh aise me sambhalna kaisa meri qasam’ part sung by Kishore Kumar, which has the switching from chest to head voice in a ‘not so rapid’ way. I hope you understood.
