Lots of 3's, Yet Without Musical Talent

Yes, I see the 3 as your destiny number and as your life path number. It's also one of your challenge numbers.

The number 3 is about (among other things) creative expression as well as socializing with and supporting creative people.

Creative expression can be with music, as you suggest. It can also be in the way a person speaks or writes, paints a picture, weaves a basket, decorates a house, creates a sculpture — any expression that can be done creatively.

A 3 challenge number would tend to encourage a person to question their own creativity, even to the point of suppressing it. The way to overcome the challenge is to first accept it for what it is and then to express yourself creatively anyway in whatever ways you can with integrity.
