In Rochester, Slonimsky continued his composition and conducting studies, with [[Albert Coates (musician)|Albert Coates]] and [[Eugene Aynsley Goossens|Eugene Goossens]], and accompanied Rosing at many vocal recitals, including a performance at [[Carnegie Hall]] in October 1924. After two years, he moved to Boston, where Koussevitzky had become conductor of the [[Boston Symphony Orchestra]], and resumed his position as his pianist and now bilingual secretary. During this time, Slonimsky taught music theory at the [[Boston Conservatory]] and the Malkin Conservatory, and began to write music articles for ''The [[Boston Evening Transcript]]'', ''[[The Christian Science Monitor]]'' and the magazine ''[[The Etude]]''.<ref name="Kozinn">{{cite news|first=Allan|last=Kozinn|author-link=Allan Kozinn| title=Nicolas Slonimsky, Author of Widely Used Reference Works on Music, Dies at 101|url=https://www.nytimes.com/1995/12/27/books/nicolas-slonimsky-author-of-widely-used-reference-works-on-musicdies-at-101.html|date=December 27, 1995|work=[[The New York Times]]|page=B6}}</ref>

Slonimsky began writing songs and other incidental pieces, and performed as a piano soloist and vocal accompanist. In 1927, he formed the Boston Chamber Orchestra, for which he solicited music from contemporary composers. Slonimsky was a great champion of contemporary music,<ref name="Kozinn" /> and through his interest in performing it met [[Henry Cowell]] and [[Charles Ives]]. He conducted the world premieres of Ives' ''[[Three Places in New England]]'' in 1931 (in New York's [[The Town Hall (New York City)|Town Hall]]), [[Edgard Varèse]]'s ''[[Ionisation (Varèse)|Ionisation]]'' for thirteen percussionists in 1933, and various other works.

In 1931, Slonimsky married [[Dorothy Adlow]], art critic of ''The Christian Science Monitor''. She was active as a critic and lectured extensively around the U.S., serving on panels and art juries. They married in Paris, with Varèse as [[best man]]. Their daughter, Electra, later edited his letters and collected works.{{efn|Some of his letters, books, photos, sheet music and recordings are maintained at slonimsky.net.{{clarify|date=January 2023|reason=That site seems to be dead.}}}}

In 1932, Slonimsky conducted a series of concerts in Havana highlighting Ives, Ruggles, Cowell, [[Amadeo Roldán]] and [[Alejandro García Caturla]]. He then traveled to Paris, Berlin and Budapest to conduct further concerts. He mentioned at the time he found conducting to be "the nearest approximation to music in motion". Thanks to the popularity of these tours, he was invited to conduct five concerts in the [[Hollywood Bowl]] in the summer of 1933. These were controversial and received mixed critical reviews.
