'''{{PAGENAME}}''' ('''GS''') is a scale-building procedure first described by [[Scott Dakota]].

The notation GS(''x''1, ..., ''x''r) denotes a scale-building procedure where a ([[Periodic scale|periodic]]) scale is built by stacking ''x''1 first, ''x''2 second, ..., reducing by the scale's [[equave]] when necessary. When ''x''r is stacked, we go back to ''x''1 and start stacking ''x''1 again, then ''x''2, ... This article adopts a convention where an enumerated chord can be used instead for part or whole of the argument, where the chord's steps are generators, for example writing [[Zarlino]] as GS(4:5:6)[7], which is syntactic sugar for GS(5/4, 6/5)[7].

Currently, the study of GSs is dominated by certain [[constant structure]] GS scales, called ''guided generator sequence'' scales, which are obtained by taking a GS of detempered MOS generators and stopping the stacking procedure at the correspondibg MOS scale sizes, which yields constant scales. In such a situation, we call the (logarithmic) average of the generators the ''guide generator''.
