Scale of sounds – the term scale of sounds refers to a series of sounds arranged according to a specific pattern. Each subsequent sound creates degrees, which are marked with Roman numerals. The scale of sounds can be constructed in an ascending or descending direction.

The scale of sounds also refers to the capabilities and range of sounds produced by a given instrument or the range and capabilities of the human voice.

Currently, ancient Greek scales, church scales, contemporary scales, and other scales characteristic of a given region and folklore are distinguished.

Contemporary scales of sounds emerged during the Baroque period and largely apply to this day. They are based on the tempered system. In the Baroque period, two seven-degree scales were created, namely the minor and major scales. Based on these, the tonal system was developed, which includes 24 keys, including 12 minor and 12 major, arranged in a circle of fifths. Over time, scales that lack a tonal center also emerged. These include the twelve-tone scale (12 degrees) and the whole-tone scale (6 degrees).
