Allan Holdsworth (6 August 1946 – 15 April 2017)[1] was a British guitarist and composer. He released twelve studio albums as a solo artist and played a variety of musical styles in a career spanning more than four decades, but is best known for his work in jazz fusion.
Holdsworth was known for his advanced knowledge of music, through which he incorporated a vast array of complex chord progressions and intricate solos; the latter comprising myriad scale forms often derived from those such as the diminished, augmented, whole tone, chromatic and altered scales, among others, resulting in an unpredictable and “outside” sound. His unique legato soloing technique stemmed from his original desire to play the saxophone. Having been unable to afford one, he strove to use the guitar to create similarly smooth lines of notes. He also become associated with playing an early form of guitar synthesizer called the SynthAxe, a company he endorsed in the 1980s.
Holdsworth was cited as an influence by a host of rock, metal and jazz guitarists such as Eddie Van Halen,[2] Joe Satriani,[3] Greg Howe,[4] Shawn Lane,[5] Richie Kotzen,[6] John Petrucci,[7] Alex Lifeson,[8] Kurt Rosenwinkel,[9] Yngwie Malmsteen,[10] Michael Romeo,[11] Ty Tabor,[12] and Tom Morello.[13] Frank Zappa once lauded him as “one of the most interesting guys on guitar on the planet”,[14] while Robben Ford has said: “I think Allan Holdsworth is the John Coltrane of the guitar. I don’t think anyone can do as much with the guitar as Allan Holdsworth can.”[15]

This article is about legato in music. For other uses, see Legato (disambiguation).

In music performance and notation, legato [leˈɡaːto] (Italian for “tied together”; French lié; German gebunden) indicates that musical notes are played or sung smoothly and connected. That is, the player makes a transition from note to note with no intervening silence. Legato technique is required for slurred performance, but unlike slurring (as that term is interpreted for some instruments), legato does not forbid rearticulation. Standard notation indicates legato either with the word legato, or by a slur (a curved line) under notes that form one legato group. Legato, like staccato, is a kind of articulation. There is an intermediate articulation called either mezzo staccato or non-legato (sometimes referred to as “portato”).

In modern musical notation and tuning, an enharmonic equivalent is a note, interval, or key signature that is equivalent to some other note, interval, or key signature but “spelled”, or named differently. Thus, the enharmonic spelling of a written note, interval, or chord is an alternative way to write that note, interval, or chord. For example, in twelve-tone equal temperament (the currently predominant system of musical tuning in Western music), the notes C♯ and D♭ are enharmonic (or enharmonically equivalent) notes. Namely, they are the same key on a keyboard, and thus they are identical in pitch, although they have different names and different roles in harmony and chord progressions.

In music theory, the concept of root is the idea that a chord can be represented and named by one of its notes. It is linked to harmonic thinking—to the idea that vertical aggregates of notes can form a single unit, a chord. It is in this sense that one speaks of a “C chord” or a “chord on C”—a chord built from “C” and of which the note (or pitch) “C” is the root. When a chord is referred to in Classical music or popular music without a reference to what type of chord it is (either major or minor, in most cases), it is assumed a major triad, which for C contains the notes C, E and G. The root needs not be the bass note, the lowest note of the chord: the concept of root is linked to that of the inversion of chords, which is derived from the notion of invertible counterpoint. In this concept, chords can be inverted while still retaining their root.
In tertian harmonic theory, that is in a theory where chords can be considered stacks of third intervals (e.g. in common practice tonality), the root of a chord is the note on which the subsequent thirds are stacked. For instance, the root of a triad such as C Major is C, independently of the vertical order in which the three notes (C, E and G) are presented. A triad can be in three possible positions, a “root position” with the root in the bass (i.e., with the root as the lowest note, thus C, E, G or C, G, E, from lowest to highest notes), a first inversion, e.g. E, C, G or E, G, C (i.e., with the note which is a third interval above the root, E, as the lowest note) and a second inversion, e.g. G, C, E or G, E, C, in which the note that is a fifth interval above the root (G ) is the lowest note.
Regardless of whether a chord is in root position or in an inversion, the root remains the same in all three cases. Four-note seventh chords have four possible positions. That is, the chord can be played with the root as the bass note, the note a third above the root as the bass note (first inversion), the note a fifth above the root as the bass note (second inversion), or the note a seventh above the root as the bass note (third inversion). Five-note ninth chords know five positions, etc., but the root position always is that of the stack of thirds, and the root is the lowest note of this stack (see also Factor (chord)).

The celesta /sᵻˈlɛstə/ or celeste /sᵻˈlɛst/ is a struck idiophone operated by a keyboard. It looks similar to an upright piano (four- or five-octave), albeit with smaller keys and a much smaller sized cabinet, or a large wooden music box (three-octave). The keys connect to hammers that strike a graduated set of metal (usually steel) plates or bars suspended over wooden resonators. Four- or five-octave models usually have a damper pedal that sustains or damps the sound. The three-octave instruments do not have a pedal because of their small “table-top” design. One of the best-known works that uses the celesta is Tchaikovsky’s “Dance of the Sugar Plum Fairy” from The Nutcracker.
The sound of the celesta is similar to that of the glockenspiel, but with a much softer and more subtle timbre. This quality gave the instrument its name, celeste meaning “heavenly” in French. The celesta is often used to enhance a melody line played by another instrument or section. The delicate, bell-like sound is not loud enough to be used in full ensemble sections; as well, the celesta is rarely given standalone solos.
The celesta is a transposing instrument; it sounds one octave higher than the written pitch. Its (four-octave) sounding range is generally considered to be C4 to C8. The original French instrument had a five-octave range, but because the lowest octave was considered somewhat unsatisfactory, it was omitted from later models. The standard French four-octave instrument is now gradually being replaced in symphony orchestras by a larger, five-octave German model. Although it is a member of the percussion family, in orchestral terms it is more properly considered a member of the keyboard section and usually played by a keyboardist. The celesta part is normally written on two braced staves, called a grand staff.

A glockenspiel (German pronunciation: [ˈɡlɔkənˌʃpiːl] or [ˈɡlɔkŋ̍ˌʃpiːl], Glocken: bells and Spiel: set) is a percussion instrument composed of a set of tuned keys arranged in the fashion of the keyboard of a piano. In this way, it is similar to the xylophone; however, the xylophone’s bars are made of wood, while the glockenspiel’s are metal plates or tubes, thus making it a metallophone. The glockenspiel, moreover, is usually smaller and higher in pitch.
In German, a carillon is also called a Glockenspiel, while in French, the glockenspiel is often called a carillon. In music scores the glockenspiel is sometimes designated by the Italian term campanelli.

Carl Maria Friedrich Ernst von Weber (18 or 19 November 1786 – 5 June 1826) was a German composer, conductor, pianist, guitarist and critic, one of the first significant composers of the Romantic school.
Weber’s operas Der Freischütz, Euryanthe and Oberon greatly influenced the development of the Romantische Oper (Romantic opera) in Germany. Der Freischütz came to be regarded as the first German “nationalist” opera, Euryanthe developed the Leitmotif technique to an unprecedented degree, while Oberon may have influenced Mendelssohn’s music for A Midsummer Night’s Dream and, at the same time, revealed Weber’s lifelong interest in the music of non-Western cultures. This interest was first manifested in Weber’s incidental music for Schiller’s translation of Gozzi’s Turandot, for which he used a Chinese melody, making him the first Western composer to use an Asian tune that was not of the pseudo-Turkish kind popularized by Mozart and others.

A leitmotif or leitmotiv /ˌlaɪtmoʊˈtiːf/ is a “short, constantly recurring musical phrase” associated with a particular person, place, or idea. It is closely related to the musical concepts of idée fixe or motto-theme. The spelling leitmotif is an anglicisation of the German Leitmotiv (IPA: [ˈlaɪtmoˌtiːf]), literally meaning “leading motif”, or perhaps more accurately, “guiding motif”. A musical motif has been defined as a “short musical idea … melodic, harmonic, or rhythmic, or all three”, a salient recurring figure, musical fragment or succession of notes that has some special importance in or is characteristic of a composition: “the smallest structural unit possessing thematic identity.”

Ernst Edler von Schuch, born Ernst Gottfried Schuch (23 November 1846, Graz – 10 May 1914, Niederlößnitz/Radebeul Dresden) was an Austrian conductor who became famous through his working collaborations with Richard Strauss at the Dresden Court Opera.

Schuch first studied law but then turned to music, trained at first by E. Stolz. He studied in Graz and later in Vienna, briefly with Felix Otto Dessoff, and started his conducting career in 1867 as Kapellmeister at Lobe’s Theatre in Breslau while the Breslau Opera was out of action following a fire.
