I have never been a big fan of very much popular music. Shows like the ‘X Factor’ I find unwatchable mainly because of the plethora of over-emotional screaming banshee’s that the show seems to attract by the bus load. I don’t deny that some may be very talented but I simply cannot enjoy the idea of a every kind of vocal pyrotechnical nonsense desperately competing in a singing olympic games. Ella Fitzgerald could sing every jazz-lick there was but also knew how to sing pure notes melodically without sliding to infinity and back. It must be possible though to perform a song (soulfully) from the heart without destroying the beauty of the original. When I used to teach singing, it was the tone (timbre), pitch and breath control that was crucial. Learn to sing every scale, arpeggio and interval perfectly (coupled with ear & rhythm training) and your style will develop naturally. All this BEFORE enrolling for the You-Tube karaoke academy. Instrumentalists learn to produce perfectly pure notes of different lengths (in tune) without vibratos, slides, trills and modulations before attempting to play like Miles Davis or Stefan Grappelli. Vocalists should start in a similar fashion.
