Modes are really important in making melodies and harmonies in music. There are seven main modes: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian. Each mode has its own special sound because of the different notes in their scales.

1. Melodic Influence:

   • Each mode highlights different notes:
     • Ionian: Sounds cheerful and bright.
     • Dorian: Has a sadder tone but with a twist—it has a raised sixth note.
     • Lydian: Also sounds bright but with a special fourth note that’s higher.
   • Melodies using these modes can create different feelings. For example, the Dorian mode is often linked to a jazzy, soulful vibe and appears in about 30% of jazz songs.

2. Harmonic Applications:

   • Each mode can make certain chords. For example:
     • Dorian helps create the ii-V-I chords, which are common in about 40% of jazz songs.
     • Phrygian can lead to Spanish-style music, often found in about 15% of Spanish songs.
   • Musicians often mix and match chords from different modes, making the music richer and more interesting.

3. Statistical Impact:

   • Studies show that around 70% of today’s music uses modes. This shows a change from the older style of music.
   • Popular songs, especially those in the Mixolydian scale, show that this mode is used a lot, with more than 30% of pop hits featuring it.

In short, modes help shape melodies and harmonies in music. They give composers many ways to create different sounds and feelings in their music.
