Alusvõtme

Alusvõtme, also known as the "foundation key" or "base key," is a fundamental concept in music theory and composition. It refers to the key that serves as the starting point or foundation for a piece of music. The alusvõtme is typically the key in which the piece is composed or the key that provides the most stability and coherence to the musical structure.

In tonal music, the alusvõtme is usually the key that contains the tonic chord, which is the primary chord that provides a sense of resolution and closure. This key is often the key that the music returns to at the end of a piece or section, creating a sense of finality and completeness.

The alusvõtme can also be used to refer to the key that is most prominent or dominant in a piece of music, even if it is not the key in which the piece is composed. This can be the case in pieces that use modal interchange or that incorporate elements from multiple keys.

In summary, the alusvõtme is a crucial concept in music theory and composition, as it provides the foundation for a piece of music and helps to create a sense of coherence and stability. It is typically the key that contains the tonic chord and is the key that the music returns to at the end of a piece or section.
