Kõrghelidest

Kõrghelidest is an Estonian term referring to overtones or harmonics in music. When a musical instrument or voice produces a sound, it does not just create a single fundamental frequency, but also a series of higher frequencies that are integer multiples of the fundamental. These higher frequencies are known as kõrghelidest.

The presence and relative strength of these overtones significantly influence the timbre or tone color of a sound. Different instruments and voices produce distinct overtone series, which is why a violin and a piano playing the same note at the same volume sound so different. The perception of warmth, brightness, or richness in a sound is largely determined by the kõrghelidest.

Musicians and acousticians study kõrghelidest to understand and manipulate sound. For example, in string instruments, the position where a string is bowed or plucked affects which overtones are emphasized. Similarly, the shape and material of a wind instrument's tubing influence the resulting overtone spectrum. The phenomenon of kõrghelidest is fundamental to music theory and acoustics, explaining the diversity and complexity of musical sounds.
