The Basics of Music Theory
Pitch and Frequency
What is Pitch?
Pitch is the perceived highness or lowness of a sound. It is what allows us to distinguish between different notes in a piece of music. Pitch is a subjective aspect of sound, and what one person perceives as high or low may be different from what another person perceives.
How is Pitch Related to Frequency?
Pitch is closely related to the frequency of a sound wave. Frequency refers to the number of vibrations per second that produce a particular sound. The higher the frequency of a sound wave, the higher the pitch will be perceived. Conversely, the lower the frequency of a sound wave, the lower the pitch will be perceived.
How is Frequency Measured in Music?
In music, frequency is typically measured in Hertz (Hz). One Hertz means that a sound wave is vibrating once per second. The standard concert pitch, or A4, which is the pitch of a violin string that is in tune with an A note on a piano, has a frequency of 440 Hz. Other musical notes have different frequencies, with higher notes having higher frequencies and lower notes having lower frequencies.
Notes and Octaves
What is a Note?
A note is the basic unit of music, and it represents a specific pitch or tone. Notes are organized on a musical staff and are represented by lines and spaces. The pitch of a note is determined by its frequency, which is measured in hertz (Hz).
What is an Octave?
An octave is a range of notes that have a frequency ratio of 2:1. In other words, the frequency of the higher note is twice that of the lower note. Octaves are an important concept in music theory because they allow us to organize and classify notes into a hierarchical structure.
How are Notes and Octaves Organized on a Musical Instrument?
On a musical instrument, notes and octaves are organized along a physical layout, such as a keyboard or a fretboard. For example, on a piano, the keys are arranged in a pattern of white and black keys that correspond to the notes of the musical scale. Each octave includes seven white keys and five black keys. The layout of the notes and octaves on a musical instrument is determined by the specific design and construction of the instrument.
Other Key Concepts in Music Theory
In addition to notes and octaves, there are many other key concepts in music theory that are essential for understanding how music works. These include scales, chords, rhythm, melody, harmony, and form. Understanding these concepts is crucial for anyone who wants to compose, perform, or analyze music.
Rhythm and Meter
What is Rhythm?
Rhythm is the pattern of sound and silence in music. It is created by the repetition of musical elements, such as melody, harmony, and rhythm, in a specific sequence. Rhythm is a fundamental element of music that gives it a sense of movement and direction.
What is Meter?
Meter is the rhythmic structure of a piece of music. It is the pattern of stressed and unstressed beats that gives music its rhythmic organization. Meter is typically represented by a series of numbers, indicating the number of beats in each measure and the type of note that gets the beat.
How are Rhythm and Meter Used in Music?
Rhythm and meter are closely related and work together to create a sense of movement and direction in music. Rhythm provides the pattern of sound and silence, while meter provides the structure of the rhythm. Musicians use rhythm and meter to create a sense of momentum and to help the listener follow the musical structure. In Western classical music, meter is typically indicated by the time signature, which shows the number of beats in each measure and the type of note that gets the beat. In popular music, rhythm and meter are often more flexible and can be varied to create different effects.
Common Music Theory Concepts
Scales and Modes
What is a scale?
A scale is a series of musical notes arranged in ascending or descending order of pitch. These notes are organized into a pattern that defines the structure of the scale. The most common scales in Western music are the major and minor scales, which form the basis for many different types of music.
What is a mode?
A mode is a type of scale that defines the character of a piece of music. In Western music, there are seven modes, each with its own unique set of notes and characteristics. The most commonly used modes are the Ionian (major) mode, the Aeolian (minor) mode, and the Dorian mode.
What are the most common scales and modes in Western music?
The most common scales and modes in Western music are:
- The major scale, which is used in many different types of music, including classical, pop, and rock.
- The minor scale, which is used in many different types of music, including classical, jazz, and blues.
- The Dorian mode, which is used in many different types of music, including classical, jazz, and blues.
- The Mixolydian mode, which is used in many different types of music, including classical, jazz, and blues.
- The Aeolian mode, which is used in many different types of music, including classical, jazz, and blues.
- The Phrygian mode, which is used in many different types of music, including classical, jazz, and blues.
- The Locrian mode, which is used in many different types of music, including classical, jazz, and blues.
Each of these scales and modes has its own unique set of notes and characteristics, which can be used to create different moods and emotions in music. Understanding the fundamentals of scales and modes is essential for any musician looking to develop their skills and understanding of music theory.
Key Signatures
What is a key signature?
A key signature is a set of sharp or flat symbols placed immediately after the clef at the beginning of a musical score. It provides information about the pitches that are considered “in key” for a particular piece of music. The key signature consists of one or more sharp or flat symbols, each of which alters the pitch of a particular note.
How do key signatures work?
Key signatures are used to indicate the tonality of a piece of music. The specific pitches that are considered “in key” depend on the key signature. For example, the key signature for C major consists of a single sharp (#) placed on the note B, indicating that B-natural is the seventh note of the scale. The key signature for A minor consists of a single flat (b) placed on the note B, indicating that B-flat is the seventh note of the scale.
How do you read a key signature?
To read a key signature, start by identifying the note that the key signature begins with. The first note of the key signature will be the note that the scale is based on. For example, the key signature for C major begins with the note C. Once you have identified the starting note, count up the sharps or flats in the key signature to determine the order of the notes in the scale. For example, the key signature for A minor has one flat (b) on the note B, so the order of the notes in the scale would be A-B-C-D-E-F-G-A.
Chords and Progressions
What is a chord?
A chord is a group of three or more notes played simultaneously. These notes are played at the same time, and they come together to create a harmony that enhances the melody of a song. The chords are the building blocks of Western music, and they are used to create a wide range of musical styles.
What is a chord progression?
A chord progression is a sequence of chords played in a specific order. These chords are played one after the other, and they create a harmonic structure that underpins the melody of a song. Chord progressions are used to create a sense of movement and direction in a song, and they are an essential part of Western music.
How are chords and progressions used in different genres of music?
Chords and progressions are used in a wide range of musical styles, from classical music to popular music. In classical music, chords and progressions are used to create a sense of structure and harmony, and they are often used to support the melody of a piece. In popular music, chords and progressions are used to create a sense of movement and direction, and they are often used to support the rhythm of a song.
In rock music, chords and progressions are often used to create a sense of tension and release, and they are used to support the rhythm of the song. In jazz music, chords and progressions are used to create a sense of improvisation and freedom, and they are often used to support the melody of a piece.
Overall, chords and progressions are an essential part of Western music, and they are used to create a sense of harmony and structure in a wide range of musical styles. Understanding the basics of chords and progressions is an important part of understanding music theory, and it can help you to appreciate the beauty and complexity of music.

What is counterpoint?
Counterpoint is the art of combining two or more independent melodic lines in a way that creates a cohesive and interesting musical texture. It is a technique used in classical music to create complex and intricate harmonies. Counterpoint involves the interplay of different melodic lines, each with its own rhythm and contour, creating a rich and dynamic sound.
How are harmony and counterpoint used in classical music?
Harmony and counterpoint are essential components of classical music. They are used to create complex and intricate harmonies that add depth and interest to a composition. In classical music, harmony is used to create a sense of balance and stability, while counterpoint is used to create a sense of movement and dynamics.
Classical composers often used harmony and counterpoint to create complex and intricate melodies that were both technically challenging and aesthetically pleasing. For example, Johann Sebastian Bach was a master of counterpoint and used it extensively in his music, creating intricate and intricate harmonies that added depth and interest to his compositions.
Overall, harmony and counterpoint are essential concepts in classical music, and understanding them is crucial for any musician or composer looking to create complex and intricate harmonies that add depth and interest to their compositions.
Form and Analysis
What is form?
In music theory, form refers to the overall structure of a piece of music, encompassing its organization and arrangement of musical elements such as melody, harmony, rhythm, and dynamics. Form is a fundamental aspect of music that defines how musical ideas are presented, developed, and ultimately resolved within a composition. It is essential to understand form in order to comprehend the overall structure and progression of a piece of music, and to analyze how musical ideas are interconnected and manipulated throughout the composition.
How do you analyze musical form?
Analyzing musical form involves examining the overall structure of a piece of music, identifying its key components, and tracing the development of musical ideas throughout the composition. This can be done by identifying the sections or movements of the piece, analyzing the relationships between these sections, and identifying the musical elements that define the character and progression of each section. Additionally, analyzing musical form may involve identifying recurring themes, motifs, or harmonic progressions that help to define the overall structure of the piece.
What are the most common forms in Western classical music?
Western classical music has a rich tradition of various forms and structures, many of which have been developed and refined over centuries of musical practice. Some of the most common forms in Western classical music include:
- Sonata form: A three-part form consisting of an exposition, development, and recapitulation, typically featuring a contrast between a first theme (usually in the tonic key) and a second theme (often in a different key).
- Rondo form: A cyclical form consisting of a main theme (the “refrain”) and one or more contrasting themes (the “episodes”), often featuring a return to the main theme at the end of each episode.
- Minuet and Trio form: A two-part form consisting of a minuet (a stately dance in 3/4 time) and a contrasting trio section, often featuring a return to the minuet at the end of the trio.
- Fugue form: A complex form involving the presentation and development of a main theme (the “subject”) and one or more contrasting themes (the “answers”), often featuring a complex interplay between these themes in a variety of voices and textures.
These are just a few examples of the many forms found in Western classical music, and understanding these forms is essential for analyzing and appreciating the structure and progression of a wide range of classical music compositions.
Musical Language and Notation
