Wikipedia:Manual of Style/Music examples

Music examples are an obviously valuable and necessary addition to Wikipedia, often superior to text. These are both far more valuable and far more free than music samples being abstract categories applicable to multiple examples without any of the copyright or other law applicable to samples.

But how should these examples be provided? Should they be provided in the most contemporary and advanced technology, for accuracy, even if that software is not accessible to the majority of users? Should it rather present less advanced and accurate examples which are available to far more users? Should it present a diversity; such as the chord apreggiated and simultaneously, or should it be as brief as possible?
