Music history, sometimes called historical musicology, is a diverse subfield of the broader discipline of musicology that studies music from a historical point of view. In theory, "music history" could refer to the study of the history of any genre of music. In practice, these research topics are categorized as part of ethnomusicology or cultural studies, whether or not they are ethnographically based; the terms "music history" and "historical musicology" refer to the history of the notated music of Western elites, sometimes called "art music". The methods of music history include source studies, philology, style criticism, musical analysis, iconography; the application of musical analysis to further these goals is a part of music history, though pure analysis or the development of new tools of music analysis is more to be seen in the field of music theory. Some of the intellectual products of music historians include peer-reviewed articles in journals, university press-published music history books, university textbooks, new editions of musical works, biographies of composers and other musicians, studies of the relationship between words and music, reflections upon the role of music in society.

Although most performers of classical and traditional instruments receive some instruction in music history, whether this is the history or art music, pop, or rock and roll, from their music teachers throughout their lessons and high school classes, the majority of formal music history courses are offered at the post-secondary level. In Canada, some music students receive training prior to undergraduate studies because examinations in music history are required to complete Royal Conservatory of Music certification at the Grade 9 level and higher Most medium and large institutions will offer music appreciation courses for non-music majors and music history courses for music majors; the two types of courses will differ in length and depth. Both types of courses tend to emphasize a balance among the acquisition of musical repertory and analysis of these works and cultural details of music and musicians, writing about music through music criticism. More specialized seminars in music history tend to use a similar approach on a narrower subject while introducing more of the tools of research in music history.

The range of possible topics is limitless. Some examples might be "Music during World War I," "Medieval and Renaissance instrumental music," "Music and politics," "Mozart's Don Giovanni, or Women and music." The methods and tools of music history are nearly as many as its subjects and therefore make a strict categorization impossible. However, a few trends and approaches can be outlined here. Like in any other historical discipline, most research in music history can be divided into two categories: the establishing of factual and correct data and the interpretation of data. Most historical research does not fall into one category but rather employs a combination of methods from both categories; the act of establishing factual data can never be separate from the act of interpretation. Archival work may be conducted to find connections to music or musicians in a collection of documents of broader interests or to more systematically study a collection of documents related to a musician. In some cases, where records and letters have been digitized, archival work can be done online.

One example of a composer for whom archival materials can be examined online is the Arnold Schoenberg Center. Performance practice draws on many of the tools of historical musicology to answer the specific question of how music was performed in various places at various times in the past. Scholars investigate questions such as which instruments or voices were used to perform a given work, what tempos were used, how ornaments were used. Although performance practice was confined to early music from the Baroque era, since the 1990s, research in performance practice has examined other historical eras, such as how early Classical era piano concerti were performed, how the early history of recording affected the use of vibrato in classical music, or which instruments were used in Klezmer music. Biographical studies of composers can give us a better sense of the chronology of compositions, influences on style and works, provide important background to the interpretation of works, thus biography can form one part of the larger study of the cultural significance, underlying program, or agenda of a work.

Sociological studies focus on the function of music in society as well as its meaning for individuals and society as a whole. Researchers emphasizing the social importance of music are sometimes called New musicologists, they may examine the intersection of music and music-making with issues such as race, gender and disability, among other approaches. Semiotic studies are most conventionally the province of music analysts rather than historia

Upsilon Scorpii, formally named Lesath, is a star located in the "stinger" of the southern zodiac constellation of Scorpius, the scorpion. Based on parallax measurements obtained during the Hipparcos mission, it is 580 light-years from the Sun. On the night sky it lies near the 1.6 magnitude star Lambda Scorpii, the two form an optical pair, sometimes called the "Cat's Eyes". Υ Scorpii is the star's Bayer designation. It bore the traditional name Lesath, from the Arabic las'a "pass of a poisonous animal". In 2016, the International Astronomical Union organized a Working Group on Star Names to catalogue and standardize proper names for stars; the WGSN approved the name Lesath for this star on 21 August 2016 and it is now so included in the List of IAU-approved Star Names.
