A dog has gatecrashed an open-air orchestra concert.

During the International İzmir Festival in the Turkish city of Ephesus, the curious pooch was spotted wandering onto the stage and looking around while the band continued to play, unfazed by the addition to their group.

Many of the members of the Vienna Chamber Orchestra - who were in the middle of performing Mendelssohn's Italian Symphony No.4 when they were interrupted by the surprise arrival - saw the dog but were determined to finish their performance and as they built up to their crescendo the dog settled down next to a violinist.

An audience member filmed the dog's adventure on stage and some of the fans could be heard laughing at the unimpressed pup.

Just before the end of the performance the dog opened its mouth and yawned, which garnered claps and cheers from the audience.

In just a few hours, the clip which was shared on social media by ABC.com received more than 5,000 likes.
