The Locrian mode is a musical mode or diatonic scale. It may be considered a minor scale

with the second and fifth scale degrees lowered a semi-tone. The Locrian mode may also be considered as a scale beginning on the seventh scale degree of any Ionian, or major scale.The Locrian mode has the formula 1, b2, b3, 4, b5, b6, b7. Its tonic chord is a diminished triad (Bdim in the Locrian mode of the diatonic scale corresponding to C major).

The Lydian is the second major scale mode after Ionian, its tonic chord is a major triad.. It starts on the forth note of the major scale or a perfect 4th from the root of the major scale. Modern usage of the Lydian mode is often implied by certain chord spellings. For example, the chords D/C or Cmaj^7#11 imply a C Lydian harmony. (D/C⁷ or C^7#11 would both imply the Lydian dominant scale, which is the same as Lydian but with a b7th note).
