  2. Clarke Studies - Wikipedia

    en.wikipedia.org/wiki/Clarke_Studies

    The second volume, published in 1912 as Clarke's Technical Studies for Cornet, includes 190 exercises divided into ten studies with notes from the author suggesting how to practice them. Each of the ten studies concludes with an exercise serving as an étude , except for the ninth study, which lacks an exercise labeled as such, and the tenth ...

  3. Tuplet - Wikipedia

    en.wikipedia.org/wiki/Tuplet

    The most common tuplet [9] is the triplet (German Triole, French triolet, Italian terzina or tripletta, Spanish tresillo).Whereas normally two quarter notes (crotchets) are the same duration as a half note (minim), three triplet quarter notes have that same duration, so the duration of a triplet quarter note is 2 ⁄ 3 the duration of a standard quarter note.

  4. Clarke's three laws - Wikipedia

    en.wikipedia.org/wiki/Clarke's_three_laws

    The second law is offered as a simple observation in the same essay but its status as Clarke's second law was conferred by others. It was initially a derivative of the first law and formally became Clarke's second law where the author proposed the third law in the 1973 revision of Profiles of the Future, which included an acknowledgement.

    Arban's Complete Conservatory Method for Trumpet is a method book for students of trumpet, cornet, and other brass instruments.The original edition, Grande méthode complète de cornet à pistons et de saxhorn), was written and composed by Jean-Baptiste Arban (1825-1889) and published in Paris by Léon Escudier in 1864.

  6. Clarke number - Wikipedia

    Incidentally, in major reference books, there was no data table titled "clarke numbers" which showed Clarke's original tables. Despite being removed from major reference books, data from Kimura(1938) and phrases such as "the Clarke number of iron is 4.70", unsourced, continue to circulate, even in the 2010s (example: [x 7]: 799 ).

    At the conclusion of the study in 1980, Neubauer reportedly feared that public opinion would be against the study, and declined to publish it. [11] The records of the study are sealed at the Yale University Library until October 25, 2065, [ 12 ] although by 2018, some 10,000 pages had been released but were heavily redacted and inconclusive.

  8. Multiplicity (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Multiplicity_(chemistry)

    [1] [2] However the multiplicity equals the number of spin orientations only if S ≤ L. When S > L there are only 2L+1 orientations of total angular momentum possible, ranging from S+L to S-L. [2] [3] The ground state of the nitrogen atom is a 4 S state, for which 2S + 1 = 4 in a quartet state, S = 3/2 due to three unpaired electrons. For an S ...

    Examples of atoms in singlet, doublet, and triplet states.. In quantum mechanics, a doublet is a composite quantum state of a system with an effective spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2.
