Echos (Greek: ἦχος [ˈixos] "sound"; pl. echoi ἦχοι [ˈiçi], Old Church Slavonic: гласъ [glasŭ] "voice, sound") is the name in Byzantine music theory for a mode within the eight mode system (oktoechos), each of them ruling several melody types, and it is used in the melodic and rhythmic composition of Byzantine chant ("thesis of the melos"), differentiated according to the chant genre and according to the performance style ("method of the thesis"). It is akin to a Western medieval tonus, an Andalusian tab', an Arab naġam (since 1400 "maqam"), or a Persian parde (since 18th century dastgah).
The noun echos in Greek means "sound" in general. It acquired the specialized meaning of mode early on in the development of Byzantine music theory since the Octoechos reform in 692.
In general, the concept of echos denotes a certain octave species, its intervallic structure as well as a set of more or less explicitly formulated melodic rules and formulae that represent a certain category of melodies within the musical genre. As such, echos is the basis for composing or improvising new melodies that belong to it, as well as for properly performing existing pieces that have been written in it. These rules include the distinction of a hierarchy of degrees (tones, notes), where certain degrees figure as cadence notes (ἑστώτες) around which the melody will revolve prominently, or on which the melody will end most of the time. However, only very late stages of the theory (19th-20th century) actually provide systematic descriptions of echoi, while earlier stages use mostly diagrams, indirect descriptions and examples. Explicit detailed descriptions must still be provided based on extensive analysis, as is the case with modal phenomena in numerous other cultures.
Echos is the eighth studio album by Switzerland-based Gothic rock band Lacrimosa. It features classically influenced Gothic-themed rock music. The title is German for "echoes". The record was released on January 27, 2003 by Hall Of Sermon.
Echos begins with an orchestral overture of 13 minutes length and continues with a mix of symphonic elements and hard rock that is typical of Lacrimosa. However the entire album is oriented towards classical instruments rather than hard electric guitars. Singer Anne Nurmi's only solo track "Apart" has been compared to music by the Cocteau Twins. Generally, the album has been seen as a typical work by Lacrimosa.
The album received positive reviews from the critics and stayed in the German charts for eight weeks peaking at position 13. The single "Durch Nacht und Flut" reached position 51 in the German charts.
Allmusic lauded the subtlety of the songs while the German Laut magazine was positive about Lacrimosa following their own concept instead of being influenced by expectations from the fans. While writing a very positive review, the German Powermetal magazine still marked that producer and composer Tilo Wolff's musical concept had begun to become too abstract and demanding for a broad audience to comprehend.
