One of my students is learning 'What Now My Love', and his book says 'Swing' - so we've used a gentle Big Band style.
However, a very good way of playing this piece is to use a 4/4 Bolero - the style that fits the theme from 'High Noon'. I can remember that at Kawai we offered players both the 3/4 Orchestral Bolero (as in Ravel's masterpiece) and the 4/4 Bolero (High Noon) when designing the rhythm section. I don' think I've found one elsewhere since then.
I've looked around on line for a 4/4 Bolero or a 'High Noon' style without success, does anyone know of one?
