Original sentence: , and "piano white-note scale" indicates the starting note for a scale of "white notes" on the piano.Although many of the names in modern music theory are the same as names used in Greece, the sequence of tones is not the same either in pitch or in interval as in the ancient Greek modes (discussed below).In the modern conception each mode is based on the usual diatonic scale but uses a different degree of the scale as its tonic or tonal center.Note that mode 'I' (Ionian) corresponds to the familiar notion of major key and 'VI' (Aeolian) is similar to the familiar minor key.There are seven such modes, depending on which degree is used for the tone center:.Tone centre degree.where "sT" represents intervals "semitone and tone" etc
Edited sentence: Although many of the names of modes in modern music theory are the same as names used for ancient Greek modes (discussed below), they do not represent the same sequences of intervals.Degree of the major scale used as the tonic.Depending on the degree chosen, this new scale is in one of the other six modes, as follows:.For example, major scales are all use the same interval sequence T-T-s-T-T-T-s, where S means one semitone and T means one tone (2 semitones).In the modern conception a mode is based on the notion of a scale: a scale can be defined by giving the tonic note and the sequence of intervals between the notes of the scale, whereas a mode is just a sequence of intervals, with the tonic note left unspecified.Note that mode 'VI' (Aeolian) is similar to the interval sequence used by familiar minor scales.Now if one starts with any major scale, a new scale is obtained by taking a different degree of the major scale to be the tonic.This interval sequence is called the Ionian or Major mode and is one of the seven modern modes.where "piano white-note scale" indicates the starting note for a scale of "white notes" on the piano that provides an example of the mode
