i hear the following thrown around: "jaco was brilliant at flying through those 1/16 notes". now, on his self-titled album, on the song "donna lee".. are those the 1/16 notes that are spoken of? because as those are fast, i don't really have a problem playing them. with the different time signatures and bpm, what is the standard here, if there is one at all? in the same respect, let's glance at semi-old-school rock/metal. iron maiden... what credentials must be in place for one to possess the 'steve harris hand'?
