There is no way your melody or rhythm can be wrong!
There is no such thing as an incorrect melody, an incorrect rhythm, an incorrect song.
There is no way that your melodic mantra or your tune can be wrong. There is no way your rhythm can be wrong. There is no way that you can have too many syllables for your tune.
The only reasons we think things like this, is because we compare ourself to the western musical standard (which is colonisation)! We compare ourselves to the colonised idea of how tunes, and melodies, and rhythms, should sound. What numbers they should fit into.
None of that is true to what music is. The brain is a musical organ. To be human is to be musical!
There is no human that is not musical. There is no person that is more musical than you. There is no person that is more musical than ANYONE. There are people who have trained and learned hugely intricate languages of an external music system - that is true. But that doesn’t change the music that every single one of us has inside us, that is available to us whenever we want it.
The trained music is not ‘better’ or ‘more musical’ than the inherent music. Sometimes we compare ourselves to those western music standards, and so we think that some people sing in tune, and some people can’t. Or that some people are musical, and some aren’t - that is a myth. It’s all a lie! Because it is true that there are people who meet a standard and that is beautiful and to be celebrated. There’s nothing wrong with that, but every single one of us is equally musical - and there is no way that your song can be wrong.
There is no way that your tune can be too simple. There is no way that you can sing out of tune when you’re singing your own song. You can only ever be out of tune if you’re comparing yourself to someone else who sung it differently to you.
Every single one of us has rhythm, has melody, has tune, has tempo, has all the elements of music inside us, available and wanting to be expressed - and when we express those elements, our nervous system is soothed, our body feels safe, our brain feels in control, because it loves music. It understands it really easily and knows what to do, it knows how to make sense of it.
So, the more often we express our inherent musicality, the safer we feel in ourselves.
