The Extended scale represents a palette of pitches that some advanced players chooses to paint their melodies. In some ways the Basic scale is just too perfect. All the notes play well together. There is no tension, no sorrow, no glee... But add a note, you have the blues, add another note, you have a medieval scale. So many styles of music are possible if one learns how too apply these additional notes. Some examples: Primary scale, Minor Pentatonic and the Blues, Mode 4 Pentatonic, Minor 6th Pentatonic, Natural fingering, 322223, Church modes, Remember when..., and The West. Although this can be musically rewarding, this also can be a frustrating pursuit because the fingering for a particular pitch can vary greatly between different flutes and flute makers. Many find it satisfying to keep with the Basic scale.

A majority of the contemporary flutes available today have been tuned to a minor key. This results in a some pitches that cannot be reached by simply opening or closing a finger hole. For instance, a couple of pitches exist between all holes closed and opening the bottom finger hole. On flutes with large finger holes, it is sometimes possible to create these notes by half-holing or quarter-holing the bottom hole. Many find such techniques unreliable, and prefer to trill through such notes. Especially if they are short notes. This trick can be found in this version of Amazing Grace.

Half-holing is represented with a slash through the particular finger hole. Quarter-holing is denoted as a partially opened finger hole. And trilling is represented with with a wavy line. Some flutes cannot play all of the higher notes because they have limited range of pitch. Since this songbook will let you select any maker for any melody, a black attention triangle will appear where a fingering does not exist for such a flute. For difficult fingering, tiny attention triangles will appear below its finger guide. If you hover the mouse cursor over these triangles, a descriptive popup will appear.
