Not called the learning scale for a reason. The major scale is a great scale for learning how music and chords work. It’s a core scale from which a majority of your core, essential scales can be derived. There are 15 major scales.

The Major Scale or Ionian scale is a diatonic scale, made up of seven distinct notes, plus an eighth which duplicates the first one octave higher. In solfege these notes correspond to the syllables “Do, Re, Mi, Fa, Sol, La, Ti/Si, (Do)”, the “Do” in the parenthesis at the end being the octave of the root.

Harmonic Analysis ( HA ) is the process used to determine the harmonic function of chords within a chord progression. A chord progression is defined as a sequence of chords, each chord has a root and has a particular chord type. The relationship of a chord's root to a scale determines its function within that scale's tonality. Once a chord's function is identified, scale selections along with chord and scale substitutions can be made. This process is called Root Movement Analysis ( RMA ).

Listening to songs and wanting to play the same songs on ukulele - that's what draws most people to the ukulele. That and it looks like a load of fun and easy too play - which it is. Then you need to actually remember the songs that you're learning so you can play them again. And, hopefully not have to read them off a sheet all the time.
