This is a driving rock loop that is 4 repetitions of a chord progression. The first is electric guitars and drums. The second adds bass and lead synth in octaves. The third adds organ pads. The fourth is the same as the first and acts as an outro.
The feeling of the music can be hopeful, epic, sad, victorious, etc.
Big Goodbye might be used for an emotional point in a film, as part of a game soundtrack, or as background in a technology ad.
