I also got 24 of 26 ... two samples were cut short omitting one or more notes that naturally would come at the end. Not being sure whether "completeness" was part of the test (probably not since the focus was "pitch") I wrongly replied "no" for those. When designing experiments it's good to point out what to do if the tests come across unexpected situations. E.g. I've witnessed QA where the verification suggestion "no RED text should appear in the generated report" would result in PASS if no report got generated in the first place.
