This phrase originated from the early days of orchestra. In the orchestra, there is a first violinist who plays the melody and is regarded as a prominent or high profile violinist. Then there is the group of second violins that play a supportive role to the lead violinist and would not be as important or honored as the lead violinist. These second group came to be referred to as second fiddles, hence we have the phrase.
