It's a reasonable question to ask.
Indulge me for a moment and I'll share a relevant story with you.
When I first moved away from my home in Pittsburgh, PA.
I moved to Florida to attend the University of Miami and pursue a Masters Degree in Jazz Performance.
As you could imagine, there were many students from different cultures who spoke different languages.
I became friends with a student who was, originally, from Cuba....but he spoke English
He and I also became friends with someone else who was from Bologna, Italy....but he spoke English also.
Even though all 3 of us were, technically, speaking English it was easy to hear that the way in which we interpreted the language and spoke it was different.
Different accents, dialect, slang that was different BUT we were ALL speaking English.
Not everyone is going to sound, look, act exactly like everyone else but we all ARE capable of understanding each other by paying attention and being aware of those differences and embracing them.
WHAT ABOUT MUSIC???
Are you speaking the language or are you just getting by with the few words, phrases you've picked up along the way?
