Suggested length of performance
A substantial piece of music will be approximately 3-5 minutes long and would need to have some significance and/or complexity in the repertoire for the genre.
What classifies as a ‘second instrument’?
As stated in the standard, the playing techniques on the second instrument must be ‘substantially different’ (Explanatory Note 7) to the first. A discussion should take place in professional forums, e.g. cluster groups, around whether violin/viola, flute/piccolo, or classical guitar/electric guitar use substantially different playing techniques.
A decision on whether the instrument can be considered a 'second' instrument may need to be made on a case-by-case basis, based on the intent of the standard.
