The Classical period, spanning roughly from 1750 to 1820, was a time of significant transformation in the world of Western music. This era saw the evolution of music from the ornate and complex styles of the Baroque period to a more balanced, structured, and expressive form. Composers like Mozart, Haydn, and Beethoven became icons of this period, and their music continues to be celebrated for its clarity, form, and emotional depth. Central to the music of the Classical period were the scales upon which it was based. These scales were not only foundational to melody and harmony but also played a crucial role in shaping the overall aesthetic of the music. This article explores the types of scales that were predominant during the Classical period, their characteristics, and their impact on the music of the time.
I. Major and Minor Scales
The Dominance of the Major Scale
The major scale was the most prominent scale used during the Classical period. This scale, characterized by a sequence of whole and half steps, creates a sound that is often described as bright, happy, and uplifting. The major scale consists of seven notes with the following pattern: whole, whole, half, whole, whole, whole, half. This pattern gives the major scale its distinctive sound, which became the foundation for much of the music of the Classical period.
Composers like Mozart and Haydn frequently employed the major scale to create compositions that were both joyful and stately. The major scale’s structure allowed for the development of clear and memorable melodies, which were often the central focus of a piece. Additionally, the major scale provided a strong basis for the harmonic progressions that were essential to the Classical style. Cadences, which are harmonic progressions that signal the end of a phrase or section, often relied on the tonic, subdominant, and dominant chords derived from the major scale.
The Expressive Power of the Minor Scale
While the major scale dominated much of the music of the Classical period, the minor scale was also extensively used. The minor scale, with its different patterns of whole and half steps, creates a sound that is often described as more somber, melancholic, or dramatic. There are three main types of minor scales: natural minor, harmonic minor, and melodic minor.
The natural minor scale follows the pattern of whole, half, whole, whole, half, whole, whole. The harmonic minor scale, on the other hand, raises the seventh degree of the natural minor scale by a half step, creating a distinctive augmented second interval between the sixth and seventh degrees. This gives the harmonic minor scale a unique, almost exotic sound. The melodic minor scale raises both the sixth and seventh degrees when ascending but reverts to the natural minor pattern when descending.
Composers of the Classical period used the minor scale to evoke a range of emotions, from introspective melancholy to intense drama. Beethoven, in particular, was known for his masterful use of the minor scale, especially in his later works, where he explored deeper emotional themes.
II. Modal Scales
The Legacy of Church Modes
While the major and minor scales were the primary scales used during the Classical period, modal scales, which originated in the medieval period, also played a role. Modes are scales that are derived from the diatonic scale but start on a different degree. The most commonly used modes in the Classical period were the Dorian, Phrygian, Lydian, and Mixolydian modes.
The Dorian mode, which starts on the second degree of the diatonic scale, has a pattern of whole, half, whole, whole, whole, half, whole. The Phrygian mode, starting on the third degree, has a pattern of half, whole, whole, whole, half, whole, whole. The Lydian mode, starting on the fourth degree, follows the pattern of whole, whole, whole, half, whole, whole, half. Finally, the Mixolydian mode, starting on the fifth degree, has a pattern of whole, whole, half, whole, whole, half, whole.
These modes were used sparingly during the Classical period, often to evoke a sense of antiquity or to create a specific mood. For instance, the Dorian mode was sometimes used to create a sense of strength or nobility, while the Phrygian mode could evoke a more exotic or mysterious atmosphere.
The Use of Modal Interchange
Another technique involving modes that became popular during the Classical period was modal interchange. This technique involves borrowing chords from a parallel mode (a mode that has the same tonic note but a different set of intervals) and incorporating them into a piece in the major or minor key. This practice allowed composers to introduce unexpected harmonic shifts and add variety to their compositions.
For example, a composer might borrow the flattened seventh degree from the Mixolydian mode while working in a major key to create a dominant seventh chord that resolves differently than expected. Similarly, a composer working in a minor key might borrow the raised fourth degree from the Lydian mode to create a brighter, more uplifting sound.
III. Chromaticism and Altered Scales
The Advent of Chromaticism
Chromaticism, which involves the use of notes outside the standard major or minor scale, became increasingly prevalent during the Classical period. This technique allowed composers to add tension, complexity, and color to their music. Chromaticism was often used to create a sense of movement or to lead smoothly from one key to another.
The chromatic scale, which consists of all twelve pitches in an octave, was not commonly used in its entirety during the Classical period. However, individual chromatic notes were frequently introduced into otherwise diatonic passages to create a sense of drama or to highlight a particular moment in the music.
Beethoven was particularly known for his use of chromaticism. In his later works, he pushed the boundaries of tonality by incorporating more chromatic notes, which often resulted in unexpected and innovative harmonic progressions. This use of chromaticism laid the groundwork for the more adventurous harmonic explorations of the Romantic period.
Altered Scales and Exoticism
In addition to chromaticism, the Classical period also saw the occasional use of altered scales. These scales, which involve the alteration of certain notes within the standard major or minor scale, were used to create specific effects or to evoke a particular mood. One such scale is the augmented scale, which alternates between major thirds and minor thirds, creating a sense of instability and tension.
Another altered scale that was sometimes used during the Classical period is the diminished scale, which alternates between whole and half steps. This scale was often used to create a sense of suspense or to highlight a moment of dramatic intensity.
These altered scales, along with the use of chromaticism, allowed composers to explore new harmonic possibilities and to push the boundaries of the tonal system that had dominated Western music for centuries.
IV. The Role of Ornamentation and Improvisation
Ornamentation and its Impact on Scale Usage
Ornamentation, which involves the embellishment of a melody with additional notes, was an important aspect of music during the Classical period. These ornaments, which could include trills, mordents, and grace notes, often involved the use of notes from outside the standard major or minor scale.
For example, a trill might involve rapidly alternating between a note from the major scale and a note from the chromatic scale, adding a sense of excitement or tension to the music. Similarly, a mordent might involve the quick introduction of a note from a neighboring scale degree, creating a sense of movement and fluidity.
Ornamentation allowed composers and performers to add their personal touch to a piece of music, and it played a significant role in the overall expression of the music. The use of notes from outside the primary scale in ornamentation also contributed to the development of more complex harmonic language during the Classical period.
Improvisation and the Flexibility of Scales
Improvisation was another important aspect of music during the Classical period, particularly in the context of cadenzas in concertos. A cadenza is a solo passage, often improvised, that allows the performer to showcase their technical skill and creativity. During a cadenza, the performer might deviate from the written music and explore different scales, modes, and harmonic possibilities.
This practice of improvisation required a deep understanding of scales and their relationships. A skilled performer could move seamlessly between different scales, incorporating elements of chromaticism, modal interchange, and ornamentation to create a unique and expressive musical statement.
The flexibility of scales in improvisation allowed for a greater range of expression and creativity, and it played a significant role in the development of the Classical style. This emphasis on improvisation and the exploration of different scales also helped to pave the way for the more expressive and individualistic music of the Romantic period.

V. Conclusion
The music of the Classical period was built upon a rich foundation of scales, each with its own unique characteristics and emotional impact. The major and minor scales provided the primary framework for melody and harmony, while modal scales, chromaticism, and altered scales allowed composers to explore new harmonic possibilities and to add depth and complexity to their music. Ornamentation and improvisation further expanded the expressive potential of these scales, allowing both composers and performers to bring their personal touch to the music. The exploration and development of these scales during the Classical period not only defined the music of the time but also laid the groundwork for the innovations that would follow in the Romantic period. The legacy of these scales continues to influence Western music to this day, serving as a testament to the enduring power and beauty of the Classical style.
