Or a 1 3 5 7 chord adds the extra 7th note, ie. Using just the notes we have in the major scale above, a chord spelling of 1 3 5 uses the 1st, 3rd and 5th notes as they are, ie. And since the above table shows the intervals of the major scale, no sharp / flat adjustments are needed. The spelling of the interval qualities in the above table will always be shown without any sharp(#) or flat(b) symbols, since these extra symbols represent the difference of the note from the major scale. You may have seen a chord expressed as 1 b3 5, for example. In music theory, note intervals can also be expressed using using a spelling or formula, which mean the same thing. are more consonant / less disonant, when played together ( harmonic interval) with, or alongside( melodic interval) the tonic note.

The difference between the perfect and major intervals is that perfect interval notes sound more perfect / pleasing to the ear than major intervals - ie. This rule is fixed all major scales in all keys, so you will never see a perfect 3rd or a major 4th interval. So the 1st, 4th, 5th and 8th are always perfect, and the rest are always major. The interval quality for each note in this major scale is always perfect or major. The table and piano diagram below show the 8 notes (7 scale major notes + octave note) in the Eb major scale together with the interval quality for each. This step identifies the interval quality and formula / spelling for each note in the major scale, then identifies the fifth note of the major scale, and decides whether the interval quality is either perfect or major. The diminished 5th interval below Bbb is Eb E-flat 5th inverted intervals Shortĥth intervals below note E-flat Intervals below Short This table inverts the above intervals, so that each link in the last column leads to note E-flat. Inverted intervals identifying note E-flat These intervals are shown below on the treble clef followed by the bass clef.

Middle C (midi note 60) is shown with an orange line under the 2nd note on the piano diagram. 5th intervals above note E-flat E-flat dim5-perf5-aug5 intervals Short

This step shows the E-flat fifth intervals on the piano, treble clef and bass clef.
