Musical context and history
The dominant seventh is central to functional harmony: a major triad plus minor seventh creates a strong tendency to resolve. It is also fundamental to blues and jazz.
How and where it is used
Use it as a dominant that pushes toward another chord, or as a stable groove color in blues, funk and rock.
In Theory view you can hear the pitch collection without depending on a specific fingering. Then switch to Piano, Guitar, Ukulele or Mandolin to see how the same notes are physically distributed on each instrument.
