Key Terms to Review (28)
Altered chord tones: Altered chord tones are notes within a chord that have been modified from their original form, typically to create tension or add color in a musical context. These alterations often include raised or lowered fifths and ninths and are especially prominent in jazz styles like bebop, where musicians frequently use them to enhance harmonic complexity and expressiveness in their improvisations.
Angular melodies: Angular melodies refer to musical lines characterized by wide intervals and dramatic leaps, often creating a sense of tension and complexity. In the context of bebop, these melodies were essential in breaking away from the smoother, more diatonic lines of earlier jazz styles, emphasizing improvisation and individual expression. Angular melodies contribute to the intricate harmonic structures typical of bebop, allowing musicians to explore advanced chord progressions and showcase their technical abilities.
Bebop standards: Bebop standards are the foundational jazz compositions that emerged during the bebop era, primarily in the 1940s, characterized by complex melodies, intricate harmonies, and fast tempos. These standards became essential in the jazz repertoire, influencing not only performers but also shaping the direction of jazz music itself by establishing new norms for improvisation and composition.
Chromatic passing tones: Chromatic passing tones are non-chord tones that connect two chord tones by a half-step movement, creating a smooth transition between them.

This practice allows for greater freedom in improvisation and expression, which is a hallmark of the bebop style, highlighting the innovative spirit of the genre.
Harmonic rhythm: Harmonic rhythm refers to the rate at which chords change in a piece of music. It plays a crucial role in shaping the overall feel and direction of the music, influencing everything from tempo to mood. In bebop, harmonic rhythm is often more complex and varied compared to earlier styles, with frequent chord changes that drive the improvisational aspect of the genre.
Improvisation Style: Improvisation style refers to the spontaneous creation of music in real-time, where musicians express their creativity by varying melodies, rhythms, and harmonies on the spot. In the context of Bebop, this style is characterized by complex chord progressions, advanced harmonic concepts, and rapid tempos, setting it apart from earlier jazz forms. The improvisation style in Bebop emphasizes individuality and the artist's personal expression, making each performance unique.
Improvisational skills: Improvisational skills refer to the ability to spontaneously create music in real-time without pre-composed material, allowing musicians to express their creativity and individuality. In jazz, these skills are vital as they enable performers to interact dynamically with one another, react to the musical environment, and develop their unique sound within a collaborative framework. This spontaneity is central to the bebop style, which emphasizes complex melodies and harmonies that challenge musicians to think quickly and inventively.
Instrumental range expansion: Instrumental range expansion refers to the broadening of the musical capabilities and expressive possibilities of instruments, allowing them to cover a wider spectrum of pitches and dynamics. In the context of bebop, this concept is crucial as it reflects the innovative techniques and approaches that musicians adopted to create more intricate and complex musical textures. This expansion enabled players to explore advanced harmonic structures and improvisational freedom, setting bebop apart from earlier jazz styles.
Melodic complexity: Melodic complexity refers to the intricate and sophisticated nature of melodies, characterized by diverse intervals, unconventional note choices, and advanced harmonic structures. In the context of bebop, this complexity is a hallmark of the genre, as musicians sought to break away from the simpler melodic lines of earlier jazz styles and instead create music that challenges listeners with its rich tonal variations and improvisational depth.
Memorization and Internalization: Memorization refers to the process of committing information to memory, while internalization involves integrating that information into one's understanding and ability to use it. In the context of jazz, these processes are crucial for musicians, particularly in styles like bebop, where intricate melodies and complex harmonies are fundamental. Musicians must not only memorize these musical elements but also internalize them to create spontaneous, innovative performances.
Offbeat accents: Offbeat accents refer to rhythmic emphases placed on the weaker beats in a measure, rather than the stronger, more traditional beats. This technique creates a syncopated feel that adds complexity and excitement to the music, making it a hallmark of jazz, especially during the bebop era. Offbeat accents contribute to the unique character of bebop by encouraging improvisation and highlighting the individual creativity of musicians.
Outside notes: Outside notes refer to pitches that fall outside the established scale or chord tones being played in a jazz context. These notes are often used by musicians to create tension, add complexity, and enhance the improvisational aspect of their performance. This technique became especially prominent during the Bebop era, where musicians sought to break away from traditional harmonic constraints and explore more adventurous melodic lines.
Polyrhythms: Polyrhythms are musical textures that involve the simultaneous combination of contrasting rhythms, typically where two or more different rhythms are played together. This complex layering of rhythms creates a rich and dynamic sound, influencing various music styles and showcasing the rhythmic diversity found in different cultural traditions.
Rhythmic development: Rhythmic development refers to the progression and evolution of rhythmic patterns within a musical composition, emphasizing complexity, variation, and innovation.

This concept is particularly important in jazz, especially within the bebop genre, where musicians often employ complex rhythms and syncopations that demand a high level of technical skill and timing. Achieving rhythmic precision allows musicians to express intricate musical ideas while maintaining a cohesive sound within an ensemble.
Rhythmic sophistication: Rhythmic sophistication refers to the intricate and complex rhythmic patterns and structures that elevate the music's emotional depth and technical prowess. In this context, it plays a vital role in shaping the bebop style, where musicians expanded their rhythmic vocabulary, incorporating syncopation, polyrhythms, and unexpected accents to create a more dynamic and engaging musical experience.
Small ensemble format: The small ensemble format refers to a musical arrangement typically featuring a limited number of performers, often focusing on a few key instruments or voices, allowing for more intricate and personalized musical expression. In jazz, this format became prominent during the bebop era, where smaller groups allowed musicians to showcase their improvisational skills and create complex harmonic structures that differed from larger orchestral settings.
Syncopation: Syncopation is a rhythmic concept where emphasis is placed on beats or parts of beats that are typically unaccented, creating an unexpected or off-beat feeling. This technique adds excitement and complexity to music, helping to define various styles and movements throughout its evolution.
Technical demands: Technical demands refer to the specific skills and abilities required to perform music at a high level, particularly in genres that emphasize complexity and virtuosity.
