E minor

Basic characteristics

The tonic triad of E minor consists of the notes E–G–B. In the natural minor diatonic system the triads built on each scale degree are typically: i (E minor), ii° (F♯ diminished), III (G major), iv (A minor), v (B minor), VI (C major), and VII (D major). Altering the raised seventh (to D♯) is common to create a dominant V chord (B major) in the harmonic minor context. More on the concept of minor scales is available at minor scale, and details on the key signature can be found at key signature.

Instrumental affinities and tuning

E minor is particularly well suited to fretted string instruments, and especially the classical guitar, because several open strings match notes of the tonic chord. In standard guitar tuning (E–A–D–G–B–E) four of the six open strings (low E, G, B, and high E) belong to the E minor triad, making resonant open voicings and drone effects easy to produce. This accessibility contributes to the key’s frequent use in solo guitar repertoire and pedagogy; see notes on classical guitar practice here.

History, repertoire, and notable usage

E minor appears across many musical periods. Composers and performers have exploited its darker coloration and practical advantages. In the Romantic and later repertoires it features in works that range from intimate piano pieces to large-scale orchestral compositions. Felix Mendelssohn is often associated with E minor in several of his works and is noted for favoring the key in some of his music (Mendelssohn). The key is also important in the keyboard and chamber literature where its sonority contrasts with brighter relative keys; its relative major key is G major (see also G major).

Modern popular music and genres

In popular and rock-oriented styles E minor is common because the low E provides a strong foundation on the guitar and bass. Heavy and hard rock musicians exploit the low E to create power-chord textures and drop tunings; for discussion of this genre usage see heavy metal. Singer-songwriters and bands often choose E minor for its blend of sombre color and idiomatic instrument response.

Practical examples and distinctions

• Scale degrees (natural): E F♯ G A B C D.
• Common triads: Em (E–G–B), B major (as V in harmonic minor), C major (VI), D major (VII).
• Relative major: G major; parallel major: E major.
• Typical uses: solo guitar pieces, song keys for guitarists, orchestral movements with a darker timbre.
