Indeed, other factors have influenced each singer’s position here, including the uniqueness of their talent, along with their influence, impact and innovative qualities.
Having said that, it’s not solely about personal preference. How do you prove that Sinatra is really better than Satchmo, or Jon Hendricks more skilful than Mel Tormé? This list, like all lists of its kind, is undoubtedly subjective. Given that they are accomplished and bona fide masters of the art of vocal jazz, it seems almost churlish to rank the best male jazz singers at all.
