Sävelaskelkaava

Sävelaskelkaava is a Finnish term that translates to "scale formula" or "interval formula." It refers to the specific sequence of intervals that define a musical scale. In Western music theory, scales are typically constructed by arranging notes in ascending or descending order, with the relationships between consecutive notes determined by the scale's formula.

Different scales are characterized by distinct sävelaskelkaavat. For example, the major scale has a formula of whole step, whole step, half step, whole step, whole step, whole step, half step (often notated as W-W-H-W-W-W-H). The natural minor scale, conversely, has the formula of whole step, half step, whole step, whole step, half step, whole step, whole step (W-H-W-W-H-W-W). These formulas dictate the characteristic sound and mood of each scale.

The concept of sävelaskelkaava is fundamental to understanding melody, harmony, and improvisation in music. It provides a framework for composers and musicians to create and identify musical structures. While the term is Finnish, the underlying principle of interval formulas is universal in music theory across different cultures, although the specific intervals and their arrangement may vary. Understanding these formulas allows for the systematic construction of various modes and other melodic patterns beyond the standard major and minor scales.
