Being a musician (my writing homework)

Being a Musician.

Guitarist, drummer, bassist, cellist, violinist: all of them are musicians. But, what do they have in common? The answer is that all of them play an instrument, and it is the definition of a musician... “ a person who plays a musical instrument”.
And now I'm going to talk about these people.
If you are a musician you don't have a strict schedule, because you don't have to go work eight hours per day five times a week. As a musician you are working all day. When you play your instrument, when you compose something, even when you are listening to music because in this case you are training your ear.

What must you do to be a musician?

Even if you have a natural talent for your instrument, there's a difference between "playing an instrument" and "being a musician." That difference involves practice. Musicians are dedicated to improve their skills and learn new things. The only way to do that is regular and serious practice.


How can I spread my music?


Well... The answer to this question is closely related to the ways of communication.
Some years ago, If you wanted to spread your band you would have to go to the radio or on television. If you couldn't go through these ways of communication, you had to keep striving by live performances. I think that it was very difficult. But now it's easier. There are new ways which can help you to spread your music. For example youtube and social media. 
Imagine that you are a musician and you have just recorded a song and you aren't famous enough to be on the radio, nowadays you can create a video and upload it to youtube. Moreover, you have the possibilty to advertise this on social media. 


The disappointing world of the music (In Uruguay at least).


Even if you're talented, even if you're a hard worker, even if you're the best piano player in your country, it's possible that you'll struggle to be heard. Being a musician can be a slog for a lot of people, and it can take a long time before the fruits of your labor start to pay off.
In addition, being a professional musician is very expensive. Getting good instruments is too expensive, and if you want to record a CD you must pay a fortune. It is disappointing.

*This was really good. There were a few errors but very understandable. I wanted to make a few corrections without changing your sentence completely. Buen trabajo!

Puedes usar "pegamento" o "cola", quizás es mejor usar "pegamento" porque "cola" tiene significados varios, sino de verdad significa "glue".
