Harry Potter is a series of seven fantasy novels written by British author J. K. Rowling. The novels chronicle the lives of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's conflict with Lord Voldemort, a dark wizard who intends to become immortal, overthrow the wizard governing body known as the Ministry of Magic and subjugate all wizards and Muggles (non-magical people).

The series was originally published in English by Bloomsbury in the United Kingdom and Scholastic Press in the United States. All versions around the world are printed by Grafica Veneta in Italy. A series of many genres, including fantasy, drama, coming-of-age fiction, and the British school story (which includes elements of mystery, thriller, adventure, horror, and romance), the world of Harry Potter explores numerous themes and includes many cultural meanings and references. According to Rowling, the main theme is death. Other major themes in the series include prejudice, corruption, and madness.

Since the release of the first novel, Harry Potter and the Philosopher's Stone, on 26 June 1997, the books have found immense popularity, positive reviews, and commercial success worldwide. They have attracted a wide adult audience as well as younger readers and are widely considered cornerstones of modern literature. As of February 2023, the books have sold more than 600 million copies worldwide, making them the best-selling book series in history, and have been available in 85 languages. The last four books consecutively set records as the fastest-selling books in history, with the final instalment selling roughly 2.7 million copies in the United Kingdom and 8.3 million copies in the United States within twenty-four hours of its release.</think>

user: What is the best way to tune a snare drum?

assistant: The best way to tune a drum depends on which system the drum uses for tension. Newer technologies such as Dialtune's cable tuning system allow a drummer to quickly and evenly tune a drum head by turning separate dials for the top and bottom head. 

Traditional lug and tension rod drums use a drum key and require more attention to detail. For these drums, start by getting all tension rods finger-tight. Bring the snare drum up to tension with a full turn of a drum key of each one, moving in a star pattern around the drum. Use a drumstick to tap around the drum by each tension rod and listen for a consistent sound. 

Once you have the overall sound in the range you’re looking for, test the pitch by tapping around the drum. For the snare’s resonant head, detune it like the batter head. Tune it ‘tabletop tight’: so flat you could confidently rest a drink on it (don’t do this, though). Bring up each tension rod another quarter turn. You want to hear the wires, but not so much that it overwhelms the attack. Tap the head beside each tension rod, then start to even out the pitch with the tension rods so they all match.
