Mutations

These (2 2/3, 1 1/3', and 1 3/5') are the most common mutations found in smaller and medium-size organs. Be certain that you understand thoroughly each one of them. If any are unclear to you, review this topic until they become clear.

Understanding mutations is an essential element in building stop combinations of all types. This topic will be discussed in detail in a future lesson. In short, mutations are particularly useful for the color they give in solo combinations. In addition, they can add strength and gravity to chorus-type combinations.
