Maro Ajemian (July 9, 1921 – September 18, 1978) was an American pianist.

Violin Concerto No. 1 may refer to any composers' first violin concerto, or to a composer's only violin concerto:
Aram Khachaturian's Violin Concerto in D minor was completed in 1940 and dedicated to the Russian violinist David Oistrakh, who premièred the concerto in Moscow on September 16, 1940.
 Oistrakh advised Khachaturian on the composition of the solo part and also wrote his own cadenza that markedly differs from the one originally composed by Khachaturian.
 The concerto was initially well received and awarded the Stalin Prize for arts in 1941.
 The work became a staple of the 20th century violin repertoire, and maintains its popularity into the 21st century.
David Fyodorovich Oistrakh (30 September [O.S. 17 September] 1908 – 24 October 1974) was a renowned Soviet classical violinist and violist.
Béla Bartók's Violin Concerto No. 2, BB 117 was written in 1937–38.
 During the composer's life, it was known simply as his Violin Concerto.
 (His other violin concerto, Violin Concerto No. 1, Sz.
 36, BB 48a was written in the years 1907–1908, but only published in 1956, after the composer's death, as "Violin Concerto No. 1, Op.

Alla Alexandrovna Kazanskaya (Russian: Алла Александровна Казанская ) (15 June 1920 – 25 June 2008) was a Russian stage and film actress.
 She began her career at the age of 18 at the Vakhtangov Theatre in Moscow.
 It was to Kazanskaya that the composer Aram Khachaturian dedicated the "Waltz" from his incidental music to Lermontov's "Masquerade".
 By the time of her death at age 88, she was the theatre's oldest working actress.
 She had received the Crystal Turandot, Russia's foremost theatre award in 2007.
Aram Khachaturian wrote his Cello Concerto in E minor in 1946 for Sviatoslav Knushevitsky.
 It was the last of the three concertos he wrote for the individual members of a renowned Soviet piano trio that performed together from 1941 until 1963.
 The others were: the Piano Concerto for Lev Oborin (1936); and the Violin Concerto for David Oistrakh (1940).
The Violin Concerto No. 3 in E major was composed by Niccolò Paganini in 1826.
 On 12 December 1826, Paganini wrote from Naples to his friend L. G. Germi that, having recently completed his Second Violin Concerto, he had now "finished orchestrating a third with a Polacca", and added: "I would like to try these concertos out on my own countrymen before producing them in Vienna, London and Paris."
 In the event, the Third Violin Concerto does not seem to have been premiered until July 1828 in Vienna.
 Since Paganini's death in 1840 concerto wasn't performed for more than a century until it was eventually rediscovered in the late 1960s and first recorded and publically performed by Henryk Szeryng in 1971.
