25 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.
Compare each mode to major or natural minor first. Find the single altered scale degree rather than memorizing seven patterns from scratch.
Look at melodic material, not just cadences, for periods. Parallel vs. contrasting depends on whether the phrases share their opening idea.
Remember form labels are usually given. If a label like "chorus" appears, use it as context rather than trying to re-derive it.
Read the explanations even when you're right. Each one reinforces a fact that often returns in a different form on the exam.
