adjusting timeline

I find that sometimes the timeline gets too compressed. IOW: If I add a new mono track, the seconds in the timeline are roughly 1 inch per second on my display, which I really like.
If i then generate a rhythm track with 120 bpm, the timeline becomes more compressed to something like 15 seconds in 2 inches, or roughly .13 inch per second.
How can i change the timeline to be more like 1"/sec?

The amount of time shown on the Timeline depends on the “zoom” level.
Zoom in to show a smaller time range
Zoom out to show a larger time range.
