The harp is a multi-stringed instrument which has the plane of its strings positioned perpendicularly to the soundboard. Organologically, it is in the general category of chordophones (stringed instruments) and has its own sub category (the harps). All harps have a neck, resonator and strings. Some, known as frame harps, also have a pillar; those without the pillar are referred to as open harps. Depending on its size, which varies, a harp may be played while held in the lap or while it stands on a table, or on the floor. Harp strings may be made of nylon, gut, wire or silk. On smaller harps, like the folk harp, the core string material will typically be the same for all strings on a given harp. Larger instruments like the modern concert harp mix string materials to attain their extended ranges. A person who plays the harp is called a harpist or harper. Folk musicians often use the term "harper", whereas classical musicians use "harpist".

Various types of harps are found in Africa, Europe, North and South America and in Asia. In antiquity, harps and the closely related lyres were very prominent in nearly all cultures. The harp also was predominant with medieval bards, troubadors and minnesingers throughout the Spanish Empire. Harps continued to grow in popularity through improvements in their design and construction through the beginning of the 20th century.

Valérie Milot is a Canadian harpist born in the province of Quebec. In 2008, she became the first harpist to win the prestigious Prix d’Europe (97th edition). Ms Milot is renowned for her mature musical instinct as well as for the strength and the refinement of her interpretations. Her first recording, called « Révélation », was released in October 2009.

Described as a “very refined” artist by the critics (La Presse, Montreal), the young Québec harpist Valérie Milot has a flawless technique and a style that is both colourful and powerful, thus challenging the clichés one associates with the instrument.

After the jury unanimously awarded her the ‘’Prize of Great Distinction’’ and the Wilfred-Pelletier bursary when she finished her studies at the Conservatoire de musique de Trois-Rivières with Caroline Lizotte, Milot pursued her training in New York with the internationally renowned harpist Rita Costanzi.

Blind Guardian is a German power metal band formed in the mid-1980s in Krefeld, West Germany. They are often credited as one of the seminal and most influential bands in the power metal and speed metal subgenres. Blind Guardian is a part of the German heavy metal scene that emerged in the mid-1980s.

The band's lyrics, written by vocalist Hansi Kürsch, are inspired by the fiction of fantasy authors such as J. R. R. Tolkien, Michael Moorcock, Robert Jordan and George R. R. Martin as well as traditional legends and epics. Over the years, a running theme has developed personifying the band members as travelling bards, leading some fans to refer to the band affectionately as "The Bards".

Blind Guardian was formed in 1984 in Krefeld, Germany, by Hansi Kürsch (vocals, bass) and Andre Olbrich (guitar) under the name Lucifer's Heritage. The band first released two demos in 1985 and 1986, despite undergoing chaotic lineup changes: Markus Dörk (guitar) and Thomen Stauch (drums) were replaced by Christof Theißen and Hans-Peter Frey, respectively. Finally, in 1987, Marcus Siepen joined and Thomen came back to form the lineup which would stay consistent for the next 18 years.
