Step 1
Diagnose which units are actually at risk
Take a short diagnostic. Sia returns an AP score range and shows which of the 8 units are losing you marks, rather than which ones feel hard.

Where the marks actually are
AP Music Theory section weights, and what that means for your plan.
Section I and Section II Part A are 45% each, so the multiple choice and the written free response are 90% of the score between them. Sight-singing is the other 10%, and it is the only part of this exam that does not improve while you read, which is why it belongs at the start of a plan rather than the end.

Syllabus order is not exam order, so Sia weights your study days by what each section of the exam is worth rather than by when it is taught. College Board publishes no exam weight for any of the eight units in this course, only a weight for each of the three exam sections, and those three figures sum to 100%. The second line under each unit name is College Board's own subtitle for that unit, not an AskSia description. Weights are taken from the published Course and Exam Description and can change between years. Last reviewed 27 August 2026.
How the AP Music Theory agent works
From unknown starting point to a plan you can follow.
Three steps turn your current standing, your target and one fixed exam date into a plan that changes as you improve. It takes about three minutes and it is free.
Step 2
Build backwards from 10 May 2027
Choose your target score. Sia assigns every study day between now and exam day, weighted by the published exam weights rather than by syllabus order.
Step 3
Practise, get marked, and re-plan
Work exam-format multiple choice and free response. Every miss produces coaching on the specific trap or the specific rubric point, then tomorrow's plan changes around it.
The loop runs after every session
- Sia measures which skills and traps cost you points.
- Your live score forecast moves with the evidence.
- The next study block is rewritten around what changed.
You have to sing it
The only AP exam where you perform, alone and recorded.
Music Theory splits into work you write and work you hear, plus two sight-singing tasks you perform unaccompanied into a recorder. Theory students revise notation and harmony for months and leave the singing until the week before, which is exactly backwards: notation improves with study, and singing only improves with reps.
Sight-singing is drilled from day one, in short reps
A minute a day beats an hour in April. Sia schedules short recorded takes early and often rather than one long session near the exam.
Aural and written skills are trained separately
Hearing an interval and spelling one are different abilities that happen to share vocabulary. Practising only the written half leaves the aural half untouched.
Recording is part of the task
Performing into a microphone under a clock is a distinct pressure. Practising in your head does not rehearse it, so every drill is recorded.
A worked question
What a marked answer actually looks like.
One question in the AP Music Theory free-response format, worked through the way the rubric reads it, with the point that goes missing flagged at each step.
Free response, figured bass
A four-chord phrase in D major, given as a figured bass. The bass line is D3, G3, A3, D3. The G3 is figured 6/5. The A3 is figured 6/4 moving to 5/3 over the same bass note. Both D3 bass notes are unfigured.
Realise the figured bass in four voices, soprano, alto, tenor and bass, and label each chord with a Roman numeral and inversion.
Unit 5: Harmony and voice leading II, chord progressions and predominant function. Written by AskSia in the published free-response format. This is not a College Board question, and AskSia does not reproduce official questions or past papers.
1Read the figures
Figures are intervals above the bass. Over G3 the 6th is E, the 5th is D and the unwritten 3rd is B, so the chord is E G B D, a ii seventh chord with its third in the bass: ii6/5. Over A3 the 6th is F# and the 4th is D, and both then step down to the 5th, E, and the 3rd, C#. That is one dominant harmony, V6/4 – 5/3, the cadential six-four. Both unfigured D3 bass notes are I in root position.
Where the point goes. Figures count intervals above the bass, not chord members. Read the 6/5 as a plain 6 and you write E G B, the seventh disappears, and every voice above that bass is then spelled from a chord the figure never asked for.
2Spell and double
In order, I, ii6/5, V6/4, V5/3, I:
Soprano D5, D5, D5, C#5, D5
Alto A4, B4, A4, A4, A4
Tenor F#4, E4, F#4, E4, F#4
Bass D3, G3, A3, A3, D3
The ii6/5 carries all four of its tones, so nothing is doubled there. The six-four doubles its bass, A. The V and both tonic chords double their roots.
Soprano D5, D5, D5, C#5, D5
Alto A4, B4, A4, A4, A4
Tenor F#4, E4, F#4, E4, F#4
Bass D3, G3, A3, A3, D3
The ii6/5 carries all four of its tones, so nothing is doubled there. The six-four doubles its bass, A. The V and both tonic chords double their roots.
Where the point goes. A cadential six-four doubles its bass. Double the 4th instead and you are holding two Ds that both have to fall to C#, which is a pair of parallel octaves you have written before you reach the next chord.
3Resolve
The seventh of the ii6/5 is D, scale degree 1, sitting in the soprano. It is held through the six-four as the 4th above the bass, then falls to C#, scale degree 7, over the 5/3. The 6th above that bass, F# in the tenor, falls the same way to E. The bass stays on A under both, and the alto holds A as a common tone.
Where the point goes. Chord spelling and the connection between chords are scored on separate lines, so a chord can be spelled perfectly and still lose the connection. Taking that D up to F# at the six-four spells every chord correctly and resolves nothing.
4Close the cadence
Into the final I the leading tone C# rises to D and the bass falls A3 to D3. The fifth of the V, E in the tenor, rises to F# rather than falling to D, so the last chord is D F# A D, complete. Checking each adjacent pair, no two voices move in parallel fifths or octaves anywhere in the phrase, and the outer voices move in contrary motion at the cadence.
Where the point goes. A final tonic may leave out its fifth, but never its third. Let that E fall to D with the rest and the chord is D, D, A, D, which has no third and is not a tonic triad any marker can accept.

Sia plans backwards from Monday 10 May 2027 and weights each part by what it is worth on the paper. Finish early, fall behind, or fix a unit and the next session changes automatically.

Three skills, one plan
Three different skills, one exam, one plan.
The free-response section is 7 written questions worth 45% and 2 sight-singing tasks worth 10%, performed unaccompanied and recorded. Notation improves with study, aural skill improves with listening, and singing only improves with reps, so Sia schedules all three separately instead of letting theory revision stand in for the other two.
- The 30 April deadline sits inside the plan, not beside it
- Written responses drafted as the program is built
- Exam revision continues while the portfolio is finished

vs. type-a-question toolsWeighted by what each part is worth
Study days are allocated by published exam weight, so a heavy part gets the hours it deserves and a light one does not.
vs. syllabus-order revisionRubric-level FRQ marking
Sia names the specific rubric point you missed rather than handing back a number out of ten.
vs. “good answer, 6/10”Free to start · $79 to finish
Prep on the free tier, then open the full bank and all practice exams for a one-time price.
vs. $80 to $200/hour tutorsWhy it runs on your desktop

Frequently asked questions
Questions, answered.
The AP Music Theory exam is on Monday 10 May 2027, in Session 2. Session 1 exams start at 8am local time and Session 2 at 12pm local time for most schools, including all schools in the lower 48 states, Hawaii and Washington DC. Late testing runs 17 to 21 May 2027. Your AP coordinator confirms where and when you sit it.
The exam is about 2 hr 40 min long. Section I is 75 multiple-choice questions, about 80 minutes, 45% of the score, and Section II is 7 written free-response questions, about 70 minutes, 45% of the score, plus 2 sight-singing tasks, about 10 minutes, 10% of the score. It is a hybrid digital exam. Calculators are not permitted.
Section I and Section II Part A are 45% each, so the multiple choice and the written free response are 90% of the score between them. Sight-singing is the other 10%, and it is the only part of this exam that does not improve while you read, which is why it belongs at the start of a plan rather than the end.
AP exams are reported on a 1 to 5 scale. Your raw marks from both sections are combined using the published weightings, then converted to the final score. There is no penalty for a wrong or blank multiple-choice answer, so leaving one blank is never correct strategy. Scores are usually released in early July, and College Board publishes the exact 2027 score-access dates in spring 2027.
In practice, Sight-singing. It is the only AP task where you perform, unaccompanied and recorded, and it is the one students practise last. Sia identifies which of these patterns is costing you marks and drills that specific pattern rather than the topic in general.
No, and no legitimate tool has them. Official AP questions are the copyrighted property of College Board. Every AskSia question is written by AskSia to the published Course and Exam Description format, then selected for the individual student based on the skills they are losing marks on. What matches the real exam is the format: the same question types, section timing, weighting and rubric structure. AP is a registered trademark of the College Board, which does not endorse or review AskSia.

Yes. From 2027 every AP exam is digital. AP Music Theory is a hybrid digital exam sat in Bluebook.
