Major 13th
Ebmaj13 is a major seventh chord built on Eb. It has a warm, stable, and slightly dreamy quality — the sound of resolution and arrival in jazz harmony. Major seventh chords appear on the I and IV degrees of major keys and are foundational to jazz piano voicing.

The major seventh chord most commonly functions as the I (tonic) or IV (subdominant) chord in a major key (Levine, The Jazz Theory Book). As the I chord, Ebmaj13 is the point of harmonic resolution — the destination of ii-V-I progressions. As the IV chord, it adds warmth and colour without the tension of dominant harmony. Jazz pianists voice major sevenths with rootless voicings to create the characteristic "Bill Evans sound" (Levine, The Jazz Piano Book).
Commonly paired with the Ionian mode (major scale) when functioning as I, or the Lydian mode (#4) when functioning as IV — the raised fourth avoids the "avoid note" of the natural fourth (Aebersold, Jazz Handbook). The Lydian sound is brighter and more modern.
Major seventh chords are typically points of resolution rather than departure. In a ii-V-I progression, Ebmaj13 is the destination (Mulholland & Hojnacki, The Berklee Book of Jazz Harmony).

Ebmaj13 is a four-note chord containing the root (Eb), major third, perfect fifth, and major seventh. It produces a lush, stable sound that defines the tonic in jazz harmony (Levine, The Jazz Theory Book).
The most common voicings are shell (root, 3rd, 7th), rootless Type A (3rd, 5th, 7th, 9th), and rootless Type B (7th, 9th, 3rd, 5th). In a band setting, Levine recommends omitting the root since the bassist plays it (The Jazz Piano Book). These are sometimes called "left-hand voicings."
Ebmaj13 is used as a tonic chord (I) or subdominant chord (IV) in jazz standards. It appears in virtually every jazz standard as a point of harmonic resolution.
Rootless voicings for major seventh chords are introduced as "left-hand voicings" with two positions (A and B) that alternate for smooth voice leading.

The Lydian mode is the preferred scale choice for major seventh chords functioning as IV, avoiding the natural fourth as an "avoid note."
