LydianThe Lydian mode stands out for its bright, uplifting sound, largely due to its raised fourth degree. It is one of the seven musical modes that originates from the major scale, starting on the fourth degree, and it features a distinctive pattern of intervals.In the Lydian scale, the steps are as follows: Whole, whole, whole, half, whole, whole, half. Starting on F (a popular choice to demonstrate Lydian, as it naturally occurs without any sharps or flats when played on the white keys of a piano), the scale is presented like this:F, G, A, B, C, D, E, FHere are the distances between the notes:

• F to G: whole step
• G to A: whole step
• A to B: whole step
• B to C: half step
• C to D: whole step
• D to E: whole step
• E to F: half step

The unique interval pattern, especially the raised fourth, gives the Lydian mode its characteristic dreamy and ethereal quality. The Lydian mode can be initiated on any note to form various Lydian scales. For example, a C Lydian scale would look like this:C, D, E, F#, G, A, B, CNote the scale is modified (F raised to F# in this case) to preserve the Lydian mode's hallmark whole and half step arrangement.
