yläsäveliä

Yläsäveliä, also known as overtones or harmonics, are the pure tones that are sounded along with a fundamental musical note. When a string is plucked, or a column of air is blown into, it vibrates not only at its fundamental frequency but also at higher frequencies that are integer multiples of the fundamental. These higher frequencies are the yläsäveliä. The combination of the fundamental and its yläsäveliä creates the unique timbre or sound quality of an instrument. The relative loudness of these yläsäveliä determines the characteristic sound of different instruments, even when they are playing the same note at the same volume. For example, a clarinet and a flute playing the same note will have different timbres because of the different strengths of their respective yläsäveliä. The study of yläsäveliä is important in acoustics and music theory. In music, skilled performers can manipulate the excitation of yläsäveliä to produce specific musical effects, such as harmonics on string instruments or multiphonics on wind instruments. The presence and intensity of yläsäveliä are crucial for the richness and complexity of musical sound.
