puolisävellintä

Puolisävellintä, also known as a microtone, is an interval in music smaller than a semitone. In Western music, the smallest standard interval is the semitone, which is the distance between two adjacent keys on a piano. Puolisävellintä refers to the notes that would theoretically fall between these standard semitones.

The concept of puolisävellintä is not new and has been explored in various musical traditions and theoretical systems throughout history. Many non-Western musical cultures utilize intervals smaller than a semitone as a fundamental part of their tuning systems and melodic practices. For example, the music of India, the Middle East, and parts of Southeast Asia commonly features intervals that can be considered microtonal.

In Western music, the use of puolisävellintä is less common but has been explored by composers seeking to expand the harmonic and melodic possibilities of their music. Some composers have experimented with quarter tones, which are literally half of a semitone, dividing the octave into 24 equal parts instead of the standard 12. This requires specialized instruments or techniques to perform.

The perception and precise intonation of puolisävellintä can vary. Instruments like the fretless guitar or certain wind instruments allow for the production of microtonal intervals. Electronic instruments and digital music production software also offer precise control over microtonal tuning. While not part of the mainstream Western musical vocabulary, puolisävellintä represents a rich area of musical exploration and diversity.
