Scale Theory
Scale Degree Names
Each degree of the diatonic scale has a name that relates to its function. Both the Major and all three forms of the minor share these terms.
1st – Tonic/Root – Tonal Center, the final resolution tone
2nd – Supertonic – One step above the tonic
3rd – Mediant – Midway between tonic and dominant
4th -Subdominant – The lower dominant, the fifth tone down from the tonic and forth up from the tonic
5th – Dominant – Called that because of its importance next to the tonic.
6th – Submediant – Lower mediant halfway between tonic and lower dominant.
7th – Leading Tone- Melodically leads to tonic
Subtonic - Referred to subtonic only in natural minor scale.
