What's the predominate note of the F minor scale?
one of the most important and distinctive notes in F minor would be Ab, i'm not sure if that's what you mean by predominant. i think there is another musical term called subdominant which is a term i don't really use but i think it means something and i think it's a chord, and not Ab, but in casual english 'predominant' just sort of means like the most important, which i guess can often be Ab, unless it's the bass you're talking about in which case it would usually be F, depending on the situation. i'm not sure if that answers your question
