How Can I Learn the Basics of Music Theory #1: Deepen Your Understanding of Music
Do you want to understand how music works? Studying music theory is a worthwhile experience that’ll deepen your understanding of music and enhance your creativity. Where should you begin? In this post, you’ll learn what the basics of music theory are and be given the resources to learn them. Keep reading How Can I Learn the Basics of Music Theory to start your musical journey today.
Please note that some topics such as scales music, modes music, and musical keys are all intertwined:
- For example, a music mode is just a special type of music scale, which is almost the same thing as a musical key. Likewise, major and minor music scales are the same thing as major and minor music modes respectively.
- Likewise, modulation relates to changing keys (i.e., music scales), but also is an important aspect of the study of harmony.
- Therefore, as you start learning music theory, be sure to look for the connections between concepts.
This post uses musical terms. For definitions, see the Glossary at the end of the article.

How Can I Learn the Basics of Music Theory #2: What are the Basics of Music?
Essentially, learning music theory is about learning the patterns that composers use to create music. It covers:
- Melody
- The Music Notes on a Scale
- Intervals
- Scales in Music
- Modes in Music
- Music Scale Degrees
- Rhythm
- Harmony/Chords
- Meter/Time Signatures
- Form
You can use music theory to analyze (i.e., understand) music.

Melody:
Melody happens when you play notes in succession one after the other.
One of the most basic areas of music theory is the study of music notes on a scale:
- Look at the keyboard diagram above, and you’ll see that the white keys (the naturals) are named for the first seven letters of the alphabet.
- Originally, those were the only music notes on the scale.
- Then, the mediaeval music theorists realized that they needed more music notes for their scale. (This is where the black keys, or accidentals, came from.)
The next theory concept is that an interval is a distance between music notes. Let’s start with the white key intervals:
- C to D is a second
- C to E is a third
- C to F is a fourth
- And so on until you get to C to C, which we call an octave.
- The octave spans eight notes on the keyboard.
- This works for any pair of white keys.
- You’re just counting the white keys on the keyboard.
However, when the music theorists realized they needed more music notes for the scale, they also realized that they needed to break the keyboard into smaller intervals:

How Can I Learn the Basics of Music Theory #4: Rhythm, Meter, Keys, Modulation, Harmony, and Form
The following basic music theory topics cover timing, chords, song structure, keys, and modulation.
Rhythm:
Simply put, rhythm is playing notes in time.
For basic clapping exercises:
Time Signatures:
Time signatures organize the notes into groupings of beats. Time signatures can also be called meter signatures because they “meter” (or measure) the number of beats:
Simple meter:
Compound Meter:
Harmony:
- Harmony refers to what notes work well together.
- So, harmony happens when you play two or more notes at the same time.
- The term chord comes from the same root as the word accord (meaning agreement) and is almost synonymous with harmony. However, a chord has three or more notes.
Harmonizing a Melody:
Harmonic Analysis:
- Explain Roman Numeral Analysis in Layman’s Terms for Me
- Chord Progressions (Including the 12 Bar Blues)
- Tonic vs. Root in Music Theory
- What Exactly Does I7-vi7-V7 Mean?
- What’s the Deal with These iv-V-VII Chords?
Song Form:
The form defines the sections of a song: verses, choruses, bridges, etc.
Keys and Modulation:
- A key has some of the notes from the 12 chromatic notes on the keyboard diagram above.
- For example, the seven notes of the G major scale will be in the key of G. Therefore, the terms key and scale are almost synonymous.
- In addition, when you modulate, you change from one key to another.
