story : Honolulu is the capital and largest city of the U.S. state of Hawaii. It is an unincorporated part of and the county seat of the City and County of Honolulu on the island of Oahu. The city is the main gateway to Hawaii and a major portal into the United States. The city is also a major hub for international business, military defense, as well as famously being host to a diverse variety of east-west and Pacific culture, cuisine, and traditions.

Honolulu is the most remote city of its size in the world and is the westernmost major U.S. city. For statistical purposes, the U.S. Census Bureau recognizes the approximate area commonly referred to as "City of Honolulu" (not to be confused with the "City and County") as a census county division (CCD). Honolulu is a major financial center of the islands and of the Pacific Ocean. The population of the city of Honolulu was 337,256 as of the 2010 census, while the Honolulu CCD was 390,738 and the population of the consolidated city and county was 953,207.

"Honolulu" means "sheltered harbor" or "calm port". The old name is said to be Kou, a district roughly encompassing the area from Nuuanu Avenue to Alakea Street and from Hotel Street to Queen Street which is the heart of the present downtown district.

Now, solve this instance: story: A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions. It is to be distinguished from "musical form" and "musical style", although in practice these terms are sometimes used interchangeably. Recently, academics have argued that categorizing music by genre is inaccurate and outdated.

Music can be divided into different genres in many different ways. The artistic nature of music means that these classifications are often subjective and controversial, and some genres may overlap. There are even varying academic definitions of the term "genre "itself. In his book "Form in Tonal Music", Douglass M. Green distinguishes between genre and form. He lists madrigal, motet, canzona, ricercar, and dance as examples of genres from the Renaissance period. To further clarify the meaning of "genre", Green writes, "Beethoven's Op. 61 and Mendelssohn's Op. 64 are identical in genre both are violin concertos but different in form. However, Mozart's Rondo for Piano, K. 511, and the "Agnus Dei" from his Mass, K. 317 are quite different in genre but happen to be similar in form." Some, like Peter van der Merwe, treat the terms "genre" and "style" as the same, saying that "genre" should be defined as pieces of music that share a certain style or "basic musical language." Others, such as Allan F. Moore, state that "genre" and "style" are two separate terms, and that secondary characteristics such as subject matter can also differentiate between genres. A music genre or subgenre may also be defined by the musical techniques, the style, the cultural context, and the content and spirit of the themes. Geographical origin is sometimes used to identify a music genre, though a single geographical category will often include a wide variety of subgenres. Timothy Laurie argues that since the early 1980s, "genre has graduated from being a subset of popular music studies to being an almost ubiquitous framework for constituting and evaluating musical research objects"., question: Which pieces did he argue with the same genre but had different forms?
