The Book of Psalms (Tiberian: Təhillîm; Modern: Tehillim, תְהִלִּים, or "praises"), commonly referred to simply as Psalms, is a book of the Hebrew Bible, the Christian Bible, and the Islamic Zabur. Taken together, its 150 poems "express virtually the full range of Israel's religious faith."

The word psalms is derived from the Greek Ψαλμοί (Psalmoi), perhaps originally meaning "music of the lyre" or "songs sung to a harp" and then to any piece of music. From psallein "play upon a stringed instrument" and then to "make music in any fashion".

The Book of Psalms in its current, most commonly used form consists of 150 songs and prayers referred to individually as psalms and referenced by chapter and verse. They each have a poetic character with frequent use of parallelism. In addition to the title of the collection, which translates as "song" or "hymns" from both Hebrew and Greek, superscriptions (or headings) in many of the Psalms provide musical references and some direction, in some cases even references to melodies that would have been well known by early congregations; however, no musical notation has survived. Songs that can be identified as such in the Psalms include songs of thanksgiving (e.g., Ps 30), hymns of praise (e.g., Ps 117) and royal psalms, which may have been used in coronations and weddings. Identification of some psalms as prayers is also seen within the text, for example in the conclusion to Psalm 72, "The prayers of David son of Jesse are ended." The largest category of Psalms, though not grouped as such in the text, is that of lament (expressions of complaint and pleas for help from God). There appears to also have been an instructional function of the psalms as seen in their references to the law (e.g., Ps 1 and 119).

Leonard Bernstein ( /ˈbɜrnstaɪn/ US dict: bûrn′·stīn; August 25, 1918 – October 14, 1990) was an American composer, conductor, author, music lecturer and pianist. He was among the first conductors born and educated in the United States of America to receive worldwide acclaim. According to The New York Times, he was "one of the most prodigiously talented and successful musicians in American history."

His fame derived from his long tenure as the music director of the New York Philharmonic, from his conducting of concerts with most of the world's leading orchestras, and from his music for West Side Story, as well as Candide, Wonderful Town, On the Town and his own Mass.

Bernstein was also the first conductor to give numerous television lectures on classical music, starting in 1954 and continuing until his death. In addition, he was a skilled pianist, often conducting piano concertos from the keyboard.

As a composer he wrote in many styles encompassing symphonic and orchestral music, ballet, film and theatre music, choral works, opera, chamber music and pieces for the piano. Many of his works are regularly performed around the world, although none has matched the tremendous popular and commercial success of West Side Story.

Igor Fyodorovich Stravinsky (sometimes spelled Strawinsky or Stravinskii; Russian: Игорь Фёдорович Стравинский, transliterated: Igorʹ Fëdorovič Stravinskij; Russian pronunciation: [ˌiɡərʲ ˌfʲjodɐrɐvʲɪtɕ strɐˈvʲinskʲɪj]; 17 June [O.S. 5 June] 1882 – 6 April 1971) was a Russian, and later French and American composer, pianist and conductor. He is acknowledged by many as one of the most important and influential composers of the 20th century.

Stravinsky's compositional career was notable for its stylistic diversity. He first achieved international fame with three ballets commissioned by the impresario Sergei Diaghilev and first performed in Paris by Diaghilev's Ballets Russes: The Firebird (1910), Petrushka (1911) and The Rite of Spring (1913). The Rite of Spring, which provoked a riot during its premiere, transformed the way in which subsequent composers thought about rhythmic structure and was largely responsible for Stravinsky's enduring reputation as a musical revolutionary who pushed the boundaries of musical design. His so-called Russian phase was followed in the 1920s by a period in which he turned to neoclassical music. The works from this period tended to make use of traditional musical forms (concerto grosso, fugue and symphony). They frequently concealed a vein of intense emotion beneath a surface appearance of detachment or austerity and often paid tribute to the music of earlier masters, for example J.S. Bach and Tchaikovsky. In the 1950s, Stravinsky adopted serial procedures. His compositions of this period shared traits with examples of his earlier output: rhythmic energy, the construction of extended melodic ideas out of a few two- or three-note cells and clarity of form, of instrumentation and of utterance.

Anna Riva (1923–2005) was the pen name of Dorothy Spencer, who was a well-known American occult author and manufacturer of hoodoo spiritual supplies. According to Catherine Yronwode, "Anna Riva" was a nom de plume that this author used only in her writing and business; Anna was her mother's name and Riva was her daughter's name.

In Spiritual Merchants, Carolyn Morro Long described how the "1970s and 1980s saw the publication of a new crop of spell books" for products available from the same companies selling the books. "The best-known of these writers is the extremely prolific Dorothy Spencer, who writes under the name 'Anna Riva.'"

When Spencer retired in the late 1990s, her company, International Imports of Los Angeles, was purchased by Indio Products. The owner of Indio Products, Marty Meyer, stated that the woman known as Anna Riva was suffering from Alzheimer's disease in 2000. In Spiritual Merchants (2001), Carolyn Long wrote "Dorothy Spencer is now quite elderly and, unfortunately, suffers from Alzheimer's disease, so I was unable to interview her."
