Musical Movements: From Nationalism to Jazz (1900-1945)

Musical Transitions

Nationalism

This style is based on legends, folk songs, and melodies that capture the spirit of each country. The melody is composed of traditional sounds, often utilizing the repetition of notes. The harmony follows classic rules, while the rhythm remains regular and soft, performed by traditional orchestras.

Impressionism

A parallel movement to Impressionist painting, this suggestive music aims to describe visual images, sensations, and unique atmospheres. Key characteristics include:

• Melody: Blurred, short, and fragmentary, with an alternation of consonant and dissonant sounds.
• Harmony: Features a mix of discords and consonant chords.
• Rhythm: Lacks clear rhythmic patterns.
• Timbre: Utilizes unfamiliar sounds from traditional instruments.

Postromanticism

Musicians of this style follow the Romantic tradition, utilizing large, colorful orchestras designed to evoke deep emotional responses from the audience.

Music Before 1945

Neoclassicism

This music is based on traditional musical ideas but includes a wide range of interpretations:

• Strong Syncopated Rhythms (e.g., Stravinsky's The Rite of Spring): In this ballet, the entire orchestra functions as a percussion section. The music is fierce and disturbing, featuring short, fragmentary melodies with dissonant intervals. The harmony includes extreme dissonances and note clusters, while the rhythm is vigorous, dynamic, and utilizes ostinatos (energetic, repetitive rhythms).
• Simple Abstract Compositions (e.g., Satie): This music is abstract, using few suggestive notes to create magical atmospheres. The melody and harmony follow traditional rules, resulting in a regular, soft rhythm played by traditional orchestras.

Expressionism

Finding the traditional eight-note scale system too restrictive, Schoenberg developed a new system using a 12-note scale where all sounds hold equal importance, with half a tone between every two notes. The melody is short and fragmentary with dissonant intervals, the harmony is highly discordant, and the rhythm lacks clear patterns.

Jazz

Jazz consists of simple musical ideas extended and developed through improvisation. It emerged from a mixture of African American slave songs (blues) and European melodies and instruments. Jazz bands typically include a rhythmic section (bass, piano) and brass instruments (trumpet, saxophone). Its sound is reminiscent of the Baroque Ground bass, featuring traditional melodies and harmonies.
