Introduction to Music Theory Basics

Music theory is the study of how music works and consists of a set of rules governing the structure and composition of music. It looks at many different aspects, from the basics of melody and harmony to more complex concepts like chord progressions, improvisation and arrangement. Understanding music theory is an important part of any musician’s skill set, as it helps inform every aspect of their playing and writing.

At its core, music theory consists of three basic concepts – notes, scales, and chords. Each of these components is fundamental to understanding the structure of music.


Notes are the building blocks of melody and harmony. A note is a specific pitch lasting for a specific duration. Notes are organized along a scale or system of pitches called a key. Different keys make use of various combinations of notes, which can create entirely different moods and sounds.


Scales are a set of tones that move in a logical order based on the size of the intervals between them. The most common scales used in Western music include Major, Minor, Blues, and Dorian. Each scale contains different notes and produces different sounds.


Chords are combinations of 3 or more notes that produce a specific sound and mood. Chords can be played on multiple instruments, including guitar, keyboard, and bass. While there are numerous types of chords, the most common are Major and Minor chords.

By understanding the fundamentals of music theory, including notes, scales, and chords, you can start to develop a more comprehensive understanding of how music works. In the following sections, we will take a closer look at each of these concepts in detail.

Overview of Common Scales

Scales are collections of musical notes that share the same tonal family and connection. There are several common scales often used in contemporary music, such as Major and Minor scales, Blues scales, and Modal scales.

Major Scale

The Major scale is widely considered the most basic, and most important, scale in Western music theory. It consists of seven notes, each with a prescribed interval of semitones between them. The Major scale is constructed starting on the first note of a scale (called the root note) and ascending following the pattern of two whole tones, followed by one semitone, then two more whole tones and one final semitone.

Minor Scale

The Minor scale is closely related to the Major scale and shares the same seven notes. What distinguishes it from a Major scale is its unique intervals. The Minor scale is constructed using a pattern of one and a half tones, then a tone, then one and a half tones, then a tone and a half and finally another tone.

Blues Scale

The Blues Scale is an expanded form of the Minor Scale, with a few additional blue notes added to it. This scale uses the same notes and intervals as the Minor scale, but with the addition of the flatted fifth and sometimes the flat ninth. These added notes give the Blues Scale its signature bluesy sound.

Modal Scales

Modal Scales are scales that are built off of the Major and Minor scales. These scales are formed by changing one (or more) of the intervals from the Major/Minor scale to create a new scale with a slightly different sound and feel. For example, the Dorian mode is a modal scale derived from the Minor scale that has a distinctive sound that is often used in jazz and blues styles.

Understanding Musical Notation

Music notation is the way that we record sounds and notes on paper so that they can be shared and understood. It helps us to communicate ideas, plan out our music, and express ourselves. Music notation includes symbols, signs, and staffs used to represent music for both reading and writing. This allows musicians to understand what to play just by looking at the music written down.

Reading music notation involves being able to recognize the different symbols and structures used. Those symbols include notes, rests, time signatures, key signatures, clefs, and repeat symbols. Each of these symbols have specific meanings and uses. For example, a note can tell you the pitch, rhythm, or duration of a sound that you will need to play.

Notation also uses staffs to organize and write down all of the information that is needed. This makes the music easier to read and understand. Most notation uses a five-line staff, which is made up of four spaces and five lines. Staffs also include bars, which separate the music into sections known as measures. This provides structure to the music so that it can be easily read and performed.

Finally, musical notation can also use symbols to tell you how to express a piece of music. These could include things like dynamic markings, articulation notes, or tempo markings. Dynamic markings tell you how loud or soft to play a note, while articulation notes tell you how to articulate certain notes. Tempo markings are typically numbers that tell you how fast or slow to play a piece of music.

By understanding the basics of musical notation, you can begin to create your own music and develop your skills as a musician. Music notation opens up a world of possibilities for making your music come to life.

Understanding Notes: Pitch, Keys, Notation Structures

Music theory is based on the idea that music is made up of notes, each of which has a certain sound and identity. Every song you hear takes its form from an array of notes and how they are organized together to create distinct sounds of harmony, melody, and rhythm.

The pitch of a note is the sound we hear when it is played. Low-pitched notes are those with a deep sound such as a bass note. High-pitched notes are those with a bright and light sound. The notes in between are medium-pitched. When notes are organized in a particular order, they become a musical scale.

Each of the notes in a particular scale will belong to a specific key. This key will control what notes are used in the scale and the overall character of the song. In Western music, there are 12 keys. Each of these keys represents a particular range of notes in the scale, giving them its own unique sound.

The notation structure is the way we write down music using symbols and lines. Musical notation is composed of two main parts: treble clef (G-clef) and bass clef (F-clef). These clefs tell us which notes are located on which staff line. Notes are written on a five-line staff, specifying a specific pitch and duration.

Knowing how to read and interpret musical notation is essential to understanding music theory. Once you understand how notes, keys, and notation structures work together, you can start writing your own music and creating your own melodies, harmonies, and rhythms.

Understanding Scales: Scale Construction and Types

Music theory revolves around understanding scales. Scales are the components of music that give it structure and form. A scale is a collection of musical notes that work together to give a piece of music its characteristic sound. Scales can be used in any genre of music, from classical to pop.

Scales are constructed using intervals, which are the distances between two notes. The most commonly used intervals in scales are major and minor thirds. A major third interval is four semitones, and a minor third interval is three semitones, or one fret on a guitar.

The most common type of scale is the major scale. It is constructed using a sequence of seven notes, starting with a note called the tonic. The other notes in the scale follow in a sequence of whole and half steps up from the tonic. Traditional western music is generally based on the major scale. Other common scales include the minor scale, the pentatonic scale, the blues scale, and the modal scales.

It is important to understand how to construct different scales and how to use them in your own music. For example, if you want a song to sound more uplifting and happy, you might use a major scale. If you want something darker and sadder sounding, a minor scale might be better. Knowing which scales to use and how to use them will help you create interesting pieces of music.

Understanding Chords: Chord Structure and Formation

Chords are musical structures that consist of at least three different notes sounded together. The notes that make up a chord are called the “root note,” the “third,” and the “fifth” (more notes can be added). This structure creates a harmonic sound when played together. While having two notes (a root note and a third) sounds interesting, the third note in the chord is what gives it its identity.

Most chords come from one of two types of scales, major or minor. Major chords will typically sound bright and cheerful while minor chords will usually sound a bit darker and sadder. Knowing this difference is important when forming chords.

Chords can also be divided into triads (three-note chords) and seventh chords (four-note chords). Triads will usually consist of a root note, a third, and a fifth while seventh chords will add an additional fourth note, a seventh. These seventh notes add a lot of complexity and depth to a chord and can be used to create many different effects.

To form a chord, simply take the root note and start counting up the scale with whole steps and whole tones until you reach the desired notes. For instance, if you’re in the key of C, a C major chord would be formed with the notes C – E – G. If you wanted to make a C7 chord you would add a Bb to the mix.

Understanding chords and the structure behind them is important for any musician. Knowing the basics of how chords are constructed and which notes each chord consists of can help you create more interesting and unique sounds in your own music.

Advanced Music Theory Concepts: Cadences, Intervals & Relationships

In music theory, cadences are essential cornerstones of composition. A cadence is a progression of chords that establishes the ending of a phrase, section, or song. There are many different types of cadences including authentic, imperfect/half, plagal, and others. Knowing how and when to use them is an important part of creating a cohesive piece of music.

Intervals are the spaces between notes in a musical scale. They can be described as major, minor, and other variations. Understanding intervals is crucial for interpreting chords and scales, as well as executing melodic lines properly.

The relationship between intervals brings us to the concept of harmony. Harmony is created when two or more notes are played simultaneously and merge into one solid sound. This can be done with chords, textures, and even melodies. Knowing and understanding how to create harmonies will help you create unique and interesting compositions.

Musical Dynamics & Expression: Dynamics & Articulations

The way that a musician plays and expresses the music can have just as much impact as the notes they are playing. Music dynamics and expression involve the way a musician controls the volume of a musical performance, as well as the kinds of techniques they use to create tension and release in the piece.

The most common form of dynamic expression is through the use of dynamics. Dynamics refer to the volume or intensity of a musical performance. In written music, dynamics are often indicated with words such as “piano” (soft) and “forte” (loud). Musicians use dynamics to emphasize certain sections of a piece, create tension between them, and to bring the overall performance to life.

Articulation is a related form of musical expression. Articulation involves the attack and release of notes, as well as the length and duration of notes. Together, dynamics and articulation are essential elements of any musical performance, and can transform a good performance into a great one.

By learning how to control dynamics and articulation, musicians can take their performances to the next level. For example, a piano melody is often drastically changed if it is played staccato rather than legato. A drumbeat can be made more intricate by varying the accents and volume of the notes. Even seemingly simple melodies can be brought to life with a proper understanding of musical expression.

Creative Development & Embellishments

Once you’ve got the basics of music theory down, honing your craft and creating beautiful music is what it’s all about. Creative development and embellishments are what help your songs stand out from the rest, by adding unique elements that make your music captivating.

One way to enhance the sound of your music is through musical ornamentation. This includes techniques such as double-stopping, trills, glissando, tremolo, vibrato, or arpeggio. All of these techniques can add a unique layer to your music and express nuanced emotion.

Another great way to expand creatively with music theory is through the use of improvisation. Improvisation is when a musician plays spontaneous notes or phrases that aren’t part of the currently written music. For example, when a jazz musician is soloing they are not playing from the sheet music, but instead are creating their own melodic patterns in real-time. Improvising allows for creativity and spontaneity, while still making use of music theory principles.

Lastly, another way to improve your craft is by understanding harmonic color. Harmonic color refers to the relationship between various chords. When you understand how certain chords sound in combination, you can use this knowledge to create interesting harmonic progressions and chord progressions. By listening to different styles of music and analyzing the chord progressions, you can learn more about how to use different chords and scales to create unique sounds.

Music theory offers a whole world of possibilities for creative musical exploration. By mastering the building blocks of music theory, understanding notes, scales, chords, and more, you can start to unlock the door to unique musical ideas!
