Nothing against yodelling at all, been listening to it since my very early 'Jimmy Rodgers, The singing Brakeman' days. Variations of yodelling techniques extend far beyond mountain herdsmen and are to be found in different forms throughout the world.
Experimentation in vocal techniques is not only "perfectly all right", it can be an essential part of the development and extension of the voice; have tried it and failed miserably.
Far from taking it too seriously, I thought I might introduce a touch of humour - however weak - sorry.
