The Federasie van Afrikaanse Kultuurvereniginge (FAK), translated Federation of Afrikaans cultural societies, was founded in 1929.
Hartman had already served on the dynamic music committee of the FAK since 1944.
In 1955 he was appointed head of this committee, a position he retained until 1981.
Over the following decades Hartman and his committee made significant strides in producing popular Afrikaans song books, presenting courses for school music, arranging competitions for choirs and awarding bursaries for deserving musicians.

In 1960 Hartman was appointed head of music at the SABC, a newly created position.
This resulted in a scaling down of his conducting load and his being sent to Europe to investigate management models and recruit orchestra players.
It was the first of a number of such visits to Europe.
Upon his return home he initiated more projects for light music as well as ethnic Afrikaans music (Boeremusiek).
For the former projects international artists Mantovani and Jos Cleber were involved.

The next two decades Hartman’s career at the SABC saw him becoming principal conductor in 1964 and later head of music again in 1967 until 1977.

He was a long time friend and associate of Hans Adler (Chairman of the Johannesburg Musical Society, and well known for his keyboard instrument collection and extensive library, later willed to Witwatersrand University, where Hartman had just earlier become head of music) and their co-operation led to many years of concerts and SABC recordings by the finest overseas musicians.

Classical musicians who accepted invitations by the SABC to perform or conduct in South Africa in the sixties and seventies included Radu Aldulescu, Henk Badings, Michel Block, Erling Blondell-Bengtsson, Jorge Bolet, Alfred Brendel, Frederick Brenn, Pierre Boulez, Alfredo Campoli, Edgar Cosma, Robert Craft, Marina de Gabarain, Monique de la Bruchollerie, Antal Dorati, Phillipe Entremont, Christian Ferras, Arthur Fiedler, Pierre Fournier, Josef Friedland, Eric Friedman, Pierino Gamba, Leonce Gras, Monique Haas, Piet Halsema, Jascha Horenstein, Mindru Katz, Gerald Krug, Louis Lane, Franco Mannino, Dennis Matthews, Ivan Melman, Hans Mommer, Andre Navarra, Rafael Orozco, Franco Patone, Gyorgy Pauk, Edith Peinemann, John Pritchard, Ruggiero Ricci, Witold Rowicki, Malcolm Sargent, Bela Siki, Constantin Silvestri, Abbey Simon, Ruth Slenczynska, Maria Stader, Janos Starker, Daniel Sternefeld, Karlheinz Stockhausen, Igor Stravinsky, Henryk Szering, Bryden Thomas, Sergio Varella-Cid, Tibor Varga, Tamas Vasàry, Heinz Wallberg, Ernst Wallfisch, Daniel Wayenberg, Kurt Wöss, Narciso Yepes  (Concert programmes).

Hartman was also committed to presenting South African musicians in SABC broadcasts.
Instrumentalists and vocalists were traced through auditions and offered contracts.
South African composers were commissioned to compose for broadcasting and be 'discovered'.
Stefans Grové, Arnold van Wyk, Hubert du Plessis, Roelof Temmingh and Peter Klatzow featured in this group.

His passionate desire to involve the youth in art music flowered into the founding of the South African National Youth Orchestra, in association with the South African Society of Music Teachers.
The SABC also had its own Junior Orchestra.

The inception in 1970 of the SABC Music Prize for young local performers who wished to pursue a solo career was another brain-child of Hartman’s.

As a result of Hartman’s establishing of the Opera Society of South Africa (OPSA) in 1957, opera productions in Afrikaans increased and local singers performed and shone in their roles.
Operas and oratorios were translated into Afrikaans by Hartman himself  together with his colleagues.

The SABC Orchestra visited local cities, rural towns and neighbouring countries, Mozambique and South West Africa (today Namibia) to introduce audiences to the genre.
Orchestras in Salisbury (today Harare) and Bulawayo in Rhodesia (today Zimbabwe) were conducted by Hartman in 1971, 1973 and 1976.
