Human Factors
I approached ZZZ airspace. I made my initial call to Tower and he told me to 'make left traffic for [Runway] XX' and report at the river. At the river; the Tower asked me to look for traffic on my left headed for [Runway] XY and to follow as #2. I did not confirm. At this point I looked for the traffic but could not confirm. After looking and not confirming the Tower asked if I had traffic; when I did see traffic headed for [Runway] XX I confirmed only that I had traffic. I failed to confirm the new Runway XY.As I made the turn to line up for [Runway] XX; a landing aircraft passed below me in my direction. I called the Tower to confirm my landing position and they confirmed clear to land. When I stated I had close traffic they informed me I was lined up on the wrong runway. I made a go around. After landing; I was asked to call the Tower on a possible pilot deviation. I made the call and we discussed what had happened.After reviewing the radio traffic; it is clear I was distracted attempting to locate the traffic I was to follow and my failure to read back the new runway caused me to miss the Tower change and continue on my original assigned heading. I need to improve my confirmation skills on the radio going forward to avoid confusion. Also confirm instructions or changes by writing them down.
Piper pilot reported an NMAC event during final approach to landing due to lining up on wrong parallel runway.
