Ionian mode in the context of "Musical mode"

In music, harmonization is the chordal accompaniment to a line or melody: "Using chords and melodies together, making harmony by stacking scale tones as triads".

A harmonized scale can be created by using each note of a musical scale as a root note for a chord and then by taking other tones within the scale building the rest of a chord.
For example, using an Ionian (major scale)

The major scale (or Ionian mode) is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales. Like many musical scales, it is made up of seven notes: the eighth duplicates the first at double its frequency so that it is called a higher octave of the same note (from Latin "octavus", the eighth).

The simplest major scale to write is C major, the only major scale not requiring sharps or flats:

In music theory, the harmonic major scale is a musical scale found in some music from the common practice era and now used occasionally, most often in jazz. It corresponds to the Raga Sarasangi in Indian Carnatic music, or Raag Nat Bhairav in Hindustani music.

It can be considered a major scale with the sixth degree lowered, Ionian ♭6, or the harmonic minor scale with the third degree raised.The intervals between the notes of a harmonic major scale follow the sequence below:

Dhīraśankarābharaṇaṃ, commonly known as Śankarābharaṇaṃ, is a rāga in Carnatic music. It is the 29th Melakarta rāga in the 72 Melakarta rāga system of Carnatic music. Since this raga has many Gamakās (ornamentations), it is glorified as "Sarva Gamaka Māṇika Rakti Rāgaṃ".

By scale wise, the Śankarābharaṇaṃ scale corresponds to Bilaval in the Hindustani music system. The Western equivalent is the major scale, or the Ionian mode. Hence this rāga is one of the most popular scales across the world, known with different names in different musical styles.
