Music theory study guide: one topic like scales, intervals or chords, with worked examples and exercises

Example result

Example for the Standard package

Study guide: solving linear equations, for students aged 13–14

The one rule

An equation is a balance. Whatever you do to one side, you do to the other, and the balance stays level. The goal is to get x alone on one side.

Worked example 3: the unknown on both sides

Solve 5x − 4 = 2x + 11.

  1. Move the x terms to one side: take 2x from both sides. 5x − 2x − 4 = 11, so 3x − 4 = 11.
  2. Move the numbers to the other side: add 4 to both sides. 3x = 15.
  3. Divide both sides by 3. x = 5.
  4. Check: 5 × 5 − 4 = 21 and 2 × 5 + 11 = 21. Both sides match.

Common mistake

In 3(x + 2) = 18, many students write 3x + 2 = 18. The 3 multiplies everything in the brackets: 3x + 6 = 18, so x = 4.

Exercises 7–10

  1. 4x + 3 = x + 18
  2. 2(x − 5) = 14
  3. 7 − x = 3x − 9
  4. 3(2x + 1) = 4x + 15

Answers: 7. x = 5 · 8. x = 12 · 9. x = 4 · 10. x = 6

Files: PDF and Word. The guide is for learning: we do not do homework or tests to be handed in.

Client: a parent whose daughter gets lost when an equation has brackets or the unknown on both sides. Task: a guide at middle school level that starts from the basics and builds up to those two cases. Standard package: up to 8 pages, 6 worked examples, 20 exercises with answers and a summary sheet. Excerpt below.

The client and all details are made up.

About this service

Music theory clicks once the patterns behind the names are clear. This guide takes one topic at your level, such as reading rhythms, major and minor scales, key signatures, intervals, triads and chords or simple cadences, and explains it in plain words: what it is, how to build or spot it and how it sounds in practice. Worked examples go step by step, for example counting semitones to name an interval or finding the chords of a key, and exercises with answers let the learner practise. Tell us the topic, the level or exam grade, the instrument and what is hard. You get PDF and Word files; Premium adds a test and an answer key. Notes are written by name and laid out in tables; there is no audio or engraved sheet music. The guide is for learning, and we don't do homework or exam tasks.

What is included

  • What you getA PDF and Word guide on one music theory topic: the rules in plain words, step-by-step building of scales, intervals or chords, links to your instrument, common traps and exercises with answers. From Standard, also a one-page sheet of scales, rules and terms; in Premium, a self-check test of 20 questions and a separate answer key with short explanations.
  • Patterns behind namesWhy a scale or chord is built the way it is
  • Step-by-step buildingScales, intervals and chords counted out note by note
  • Your instrumentExamples linked to the piano keys, the guitar neck or your voice
  • Common trapsEnharmonics, sharps and flats and other mix-ups
  • Exercises with answersName it, build it, find it in a key

What we need from you

The music theory topic (for example, compound time, the circle of fifths, seventh chords or modulation), the level or exam grade, the instrument the learner plays or none, whether letter names or do-re-mi are used, what the learner already knows and finds hard, the language and how the guide will be used. You may attach a syllabus or a page of exercises from your course as Word or PDF files, up to 3. Please don't send graded tasks or exam papers to be solved.

We will ask you:

  • Which music theory topic?
  • Level and instrument
  • Note names
  • What is hard, and the language?

Questions and answers

Is there sheet music or audio?

No. Notes are written by letter or syllable names and laid out in tables, so the learner can play them on their instrument. Audio and engraved scores are not included.

Does it follow a music exam syllabus?

If you name the exam grade or your music school's programme, we follow its topics and terms; check the details against the current syllabus.

Can you compose or harmonise a piece for me?

No. The guide explains the rules of harmony on examples for study. We don't compose or harmonise pieces to be handed in as the learner's own work.

Is it suitable for a child?

Yes. Give the age in the brief; for younger learners we use short steps, simple words and familiar tunes as reference points.
