In AP Music Theory, preparation is the consonant note that comes immediately before a dissonance (usually on the same pitch), setting it up so the dissonance sounds smooth and expected. It is the first stage of the preparation-dissonance-resolution pattern found in suspensions and chordal sevenths.
Preparation is the setup move in tonal music's tension-and-release game. Before a dissonant note sounds, Common Practice Era composers usually introduce that same pitch as a consonance first. That earlier consonant note is the preparation. Then the pitch is held or restruck while the harmony changes underneath it, turning it into a dissonance, and finally it resolves (almost always down by step).
You'll see this three-step pattern most clearly in suspensions, where the formula is literally preparation, suspension, resolution. For example, in a 4-3 suspension, the note that becomes the dissonant 4th was already sounding as a chord tone in the previous chord. The same logic applies to chordal sevenths. The seventh of a V7 chord sounds best when it is prepared, meaning it was a chord tone (or approached smoothly by step) in the chord before. Preparation is what makes dissonance feel earned instead of random.
Preparation shows up in two big places in the AP Music Theory course. First, in the embellishing tones material (Unit 6), where suspensions are defined by the preparation-dissonance-resolution sequence and you have to identify each stage in a score. Second, in part writing across Units 4-7, where the conventions of the Common Practice Era expect chordal sevenths to be prepared and then resolved down by step. Understanding preparation also explains the bigger expressive idea the course keeps returning to, which is that tonal music creates expectation, builds tension with dissonance, and releases it through resolution. If you can spot and write preparations correctly, you understand how dissonance actually works in this style.

A suspension is the textbook home of preparation. The dissonant note must first appear as a consonance in the previous chord, then hang over (suspend) into the new chord. No preparation, no suspension. That is what separates a true suspension from other embellishing tones like appoggiaturas, which leap into dissonance unprepared.
Chordal Seventh and Its Resolution (Units 4-7)
The seventh of a seventh chord is a built-in dissonance, so style conventions ask you to treat it like a suspension in slow motion. Prepare it as a common tone or approach it by step, then resolve it down by step. Part-writing FRQs reward this exact treatment.
Resolution (Units 4-6)
Preparation and resolution are bookends around a dissonance. Preparation is the before, resolution is the after. The whole arc is how tonal music converts dissonance from a mistake into an expressive event the listener anticipates.
Common Practice Era Conventions (Units 4-8)
Preparing dissonances is not a universal law of music, it is a style rule of roughly 1600-1900 European tonal music. The AP exam tests this specific style, which is why 'prepared dissonance' is treated as correct and unprepared dissonance often gets flagged as an error in part writing.
On multiple choice, preparation usually appears inside suspension questions. You might see a score excerpt and have to identify the preparation, the dissonance, and the resolution, or label a suspension by its interval pattern (4-3, 7-6, 9-8). Fiveable practice questions also frame it conceptually, asking how preparation and resolution of non-chord tones create tension and release in a phrase. On the part-writing FRQs, preparation matters most for chordal sevenths. When you write a V7 or other seventh chord, approaching the seventh smoothly (ideally as a held common tone) and resolving it down by step is the stylistically correct move the rubric rewards.
They sound like opposites and they basically are. A preparation is a consonant note that comes BEFORE a dissonance on the same pitch, setting it up. An anticipation is itself a nonchord tone that arrives EARLY, sounding a note of the next chord before that chord actually happens. Preparation sets up tension; an anticipation jumps ahead to the release. Memory hook: preparation looks backward to where the dissonance came from, anticipation looks forward to where the music is going.
Preparation is the consonant note that sounds immediately before a dissonance, usually on the same pitch, so the dissonance feels expected rather than abrupt.
Suspensions follow a strict three-part pattern of preparation, suspension (the dissonance), and resolution down by step.
Chordal sevenths should be prepared by a common tone or stepwise approach and then resolved down by step in AP part writing.
Preparation is a Common Practice Era convention, which is the style the AP exam tests, so unprepared dissonances often count as errors in part-writing FRQs.
Do not confuse preparation with anticipation; preparation is consonant and comes before a dissonance, while an anticipation is itself a nonchord tone that arrives early.
Preparation is the consonant note that comes right before a dissonance on the same pitch. It sets up dissonances like suspensions and chordal sevenths so they sound smooth and intentional, and it is the first step of the preparation-dissonance-resolution pattern.
No. Preparation is a consonant note that sets up a coming dissonance, while an anticipation is itself a nonchord tone that sounds a note of the next chord too early. They point in opposite directions in time.
No. Passing tones, neighbor tones, and appoggiaturas are dissonances that arrive without preparation. The dissonances that require preparation in Common Practice style are suspensions (by definition) and, ideally, chordal sevenths in part writing.
Keep the seventh as a common tone from the previous chord, or approach it by step. Then resolve it down by step in the next chord. For example, the F in a V7 chord in C major should ideally be held over from a chord that already contains F, then resolve down to E.
Preparation (the note sounds as a consonance), suspension (the note is held while the harmony changes, making it dissonant), and resolution (the note moves down by step to a chord tone). MCQs often ask you to locate all three stages in a score.
