How to Train Your Dragon: Music from the Motion Picture is a soundtrack album composed by John Powell for the film of the same name and released by Varèse Sarabande on March 23, 2010.

[5] Icelandic singer Jónsi was brought on to write and record the song "Sticks & Stones", which plays during the end credits of the film.

And Celtic music was something that Jeffrey [Katzenberg] felt had this very attractive quality to it, and a sweetness, that he thought would be wonderful for the film.

"[6]The score has traditional Scottish influences,[7] and uses instruments such as the fiddle, bagpipes, uilleann pipes, Great Irish warpipes and pennywhistle.

[8] The instrumentation of the score includes 3 flutes, 3 oboes, 3 clarinets, 3 bassoons, 12 French horns, 4 trumpets, 6 trombones, tuba, timpani, 8 percussionists, 2 harps, piano doubling celeste, SATB choir, and a string section of 30 violins, 12 violas, 10 celli and 8 double basses.

[8] Other instruments used include the sopilka and Irish flute, hammered dulcimer, gadulka, esraj, yaylı tambur, hurdy-gurdy, accordion, harmonium, Hardanger fiddle, acoustic and electric guitar, and the aforementioned fiddle, bagpipes, uilleann pipes, warpipes and pennywhistle.

Other percussion used include various cymbals, 4 gongs, an anvil, 2 sleigh bells, tambourine, mark tree, triangle, 2 shakers, garbage cans, and a pot.

[10] About one minute into the original opening version of "This is Berk", the music modulates via fast triplet arpeggios into the "warring Vikings" theme, which has Scottish influences.

[14] Christian Clemmensen, founder of Filmtracks.com and member of the IFMCA, praised the score, saying that "Powell has finally managed to create a well rounded and more easily digestible variation on his typical mannerisms for How to Train Your Dragon."

He however criticized the use of Scottish and Irish tones in a score meant for Vikings, as well as the Jónsi song "Sticks & Stones", which he felt "[drained] all the enthusiasm out of the environment created by Powell."

[18][19] British dressage rider Charlotte Dujardin prominently used music from the soundtrack for her Grand Prix Freestyle performances with her gelding Valegro.
