The tool below drills all three from your notes.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Unit 2 measuring systems, from your own notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

Paste a passage and the rules return cards from it. The course outline is invisible to the tool, so completeness is decided before you press the button.
Three minors, one signature, different jobs
Natural minor runs the key signature as written; harmonic minor raises the seventh so a leading tone pulls to tonic, opening the augmented second the exam loves to ask about; melodic minor raises six and seven going up for smooth melody and reverts coming down. Learn them as jobs, harmony wants the pull, melody wants the smoothness, and the alterations stop being arbitrary.
Relative and parallel: two ways to be related
Relative keys share a signature and differ in tonic, A minor living inside C major's accidentals a third below; parallel keys share a tonic and differ in signature, C major against C minor. Fast identification is a graded reflex: signature plus final note usually names the key, and the relative pair question, which minor hides in this major, is answered by counting down three half steps.
Intervals take two measurements, and both are graded
An interval's number comes from counting letter names inclusively; its quality, perfect, major, minor, augmented, diminished, comes from the half step count against the major scale yardstick. C to G sharp and C to A flat span the same half steps yet name differently, augmented fifth against minor sixth, because spelling decides. Number first, quality second, every time.
Melody gets a vocabulary: contour, range, motion
Conjunct melody moves by step, disjunct by leap; contour names the shape, arch, ascent, descent, wave; range spans lowest to highest. The vocabulary matters because dictation and analysis prompts ask you to describe before you notate: a described contour narrows what you hear into what you write, which is why the terms are drilled as listening tools, not trivia.
Texture counts layers; timbre names colours
Texture is the layer count: monophony one unaccompanied line, homophony melody over support, polyphony independent lines in conversation, with imitation as polyphony's giveaway. Timbre is the colour that tells a flute from an oboe on the same pitch, described by register, envelope and material. Listening questions grade the label plus the evidence you cite for it.

| System | The rule | The graded reflex |
|---|---|---|
| Natural minor | Signature as written | Aeolian shape recognised |
| Harmonic minor | Raise the seventh | Leading tone pulls home |
| Melodic minor | Raise six and seven up only | Revert on the way down |
| Relative keys | Same signature, new tonic | Count down three half steps |
| Intervals | Letters then half steps | Number and quality both |
| Texture | Count independent layers | Imitation flags polyphony |
What does AP Music Theory Unit 2 cover?
Minor scales in three forms, relative and parallel keys, interval number and quality, melodic contour vocabulary, timbre and texture.
Why does harmonic minor raise the seventh?
To create a leading tone that pulls to tonic for harmony's sake, at the cost of the augmented second between six and seven.
How do I name any interval reliably?
Two counts: letter names inclusively for the number, half steps against the major scale yardstick for the quality. Spelling decides between enharmonic answers.
What is the difference between relative and parallel minor?
Relative shares the signature with a different tonic; parallel shares the tonic with a different signature.
How do I tell homophony from polyphony fast?
Ask whether the accompaniment could stand alone: support under one melody is homophony, independent conversing lines, especially in imitation, are polyphony.
Can I build questions from my own Unit 2 notes?
Yes. The questions follow the upload: photograph these pages or attach the PDF, and nothing outside them enters the set.
