Mastering your keys will gain you flexibility, respect and a better ear.
Be the useful musician that can quickly transpose and adapt to a different key to suit everyone around you.
Some songs/parts just sound better by being in one key versus another, either because of actual frequency/resonance and/or register.
Expore the feel of the sound within you as you play the same thing in different keys.
Depending on your instrument, the octave steps / shifts / fingering might favour one key versus another.
Explore possibilities and limitations, then know what works best for a given situation.
Different keys force us to listen and think more in terms of key/interval relationships and structure, rather than note names and muscle memory in a given key.
The more we practice in different keys, the clearer this structure becomes, and the faster we learn and apply it to different keys.
Then we can build our muscle memory across different keys.
As we explore different keys, we test the limits of our instrument and our physical playing of it.
We can try (as far as possible) to understand and stretch these limitations, and to play the music faithfully, regardless of key.
To learn, listen and move between different instruments without having the instrument / musician's natural key being the limiting factor.
