With rich personal experiences as a musician, she began composing in the mid-1980s. As a composer, she was self-taught, but emphasized important encouragement from, among others, composer collegue and opera orchestra musician Eberhard Eyser.

In 1986, he made his debut as a composer with a performance of songs in Drottningholm's palace chapel. The texts were taken from poets such as Nils Ferlin, Harry Martinson, Werner Aspenström and Alf Henrikson. Otherwise, August Strindberg was an author she returned to, for example the chamber opera Fröken Julie (1990) which was staged at Confidencen (it was reprized in 1994) and Den Starkare (1991) which was played at the Rotundan at the Opera in Stockholm. The same work toured in 1993 with the Riksteatern around Sweden and was also performed in a Danish translation in Copenhagen in 1996.

Margareta Hallin's compositions has naturally often been vocal music - her own experiences were an invaluable asset there. She also performed her works herself on several occasions. A portrait CD where she performs her own music together with the clarinetist Kjell Fagéus is published on nosag (nosagCD068 ~ "I think about what I have abandoned..." ).
