For example, the product word of "aabaaab" and "xxyxyxy" is "(a,x)(a,x)(b,y)(a,x)(a,y)(a,x)(b,y)". For brevity, we can substitute each ordered pair of letters by a new single letter and say this is equivalent to the word "rrsrtrs". This construction has an obvious generalization to the product of three or more words. | For example, the product word of "aabaaab" and "xxyxyxy" is "(a,x)(a,x)(b,y)(a,x)(a,y)(a,x)(b,y)".

The importance of product words in music theory is that every [[Fokker_blocks|Fokker block]] can be expressed as the product word of two or more [[MOS scale]]s in a unique way. Fokker blocks are therefore equivalent to product words of | The importance of product words in music theory is that every [[Fokker_blocks|Fokker block]] can be expressed as the product word of two or more [[MOS scale]]s in a unique way. Fokker blocks are therefore equivalent to product words of MOS scales of the same size. If one or both of the MOS scales are rotated (into different [[mode|modes]]), then the product Fokker block scale is not always a mode, but is often a [[Dome|dome]] instead. | ||
