The idea
What is Harmony and intervals?
Harmony and intervals are the foundation of how notes combine. An interval is the distance between two notes, named by counting the letter names it spans (a third, a fifth) and qualified as major, minor, perfect, augmented or diminished according to the number of semitones. Intervals are consonant (octave, fifth, thirds, sixths) or dissonant (seconds, sevenths, the tritone), and harmony is the art of stacking and moving them so that tension resolves. Chords are built from intervals.
Where it appears: ABRSM and Trinity theory Grades 1 to 5, GCSE and A Level Music, AP Music Theory, IB Music, aural courses.
Where learners get stuck
Why Harmony and intervals is hard
Learners count semitones instead of letter names, so they call a major third a diminished fourth. Hearing an interval's quality, and understanding why the tritone sounds unstable, takes trained ears.
The picture a good explanation starts with: A keyboard with every interval from unison to octave drawn above C as a bracket, labelled with its name and semitone count, and consonant intervals shaded one colour and dissonant ones another.
A lesson, step by step
How a lesson on Harmony and intervals goes
01
Ask
Type or say "How do I work out the name of an interval?" in your own words, in any of 26 languages.
02
Plan
The tutor plans a storyboard, one picture per idea, starting with a keyboard with every interval from unison to octave drawn above C as a bracket, labelled with its name and semitone count, and consonant intervals shaded one colour and dissonant ones another.
03
Explain
It explains Harmony and intervals out loud while the picture builds step by step, pitched to your level (ABRSM and Trinity theory Grades 1 to 5 and up).
04
Interrupt
Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.
05
Check
A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.
06
Your notes
Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.

- What is the difference between a major and a minor third?
- Why does the tritone sound so tense?
Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.

Can LetMeTeach explain Harmony and intervals?
Yes. Ask in your own words and the tutor plans a lesson on Harmony and intervals: it starts with a keyboard with every interval from unison to octave drawn above C as a bracket, labelled with its name and semitone count, and consonant intervals shaded one colour and dissonant ones another. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.
