One of the easiest ways to learn tunes is to understand the circle of 5ths/4ths, and the diatonic cycle. Diatonic just means "in the key of". Get a basic music theory/fundamentals book and get a handle on the twelve major and minor keys and understand key signatures. All music can be broken down into chord progressions. Chord progressions can be analyzed by using roman numerals. The C major scale is spelled: C D E F G A B. Now if you build chords off of each scale degree, you get: C maj, d min, e min, F maj, G maj, a min, b diminished. These are the diatonic triad chords in the key of C major. I ii iii IV V vi viio. Upper case is major, lower case is minor. Diminished is usually denoted with a circle. i.e., viio Now, I IV V in the key of C major is C F G. In jazz, the ii V I progression is more common. ii V I in C major is d min7, G7 and C maj7. There is a lot more to this, but this is a good starting point for a beginner. This may be a little confusing at first, but you will understand it with some practice. Sorry if this is a little long winded.
