Two genres of music I am considering putting in my magazine that I already know quite a lot about are:

Pop - Information about music in the charts, the latest bands, your favourite artists etc.

Example of existing magazine:

• Image covers the masthead
• The main image is the biggest focus because that's what will draw readers in
• Sell lines don't cover the main image
• Centres around three colours, blue, pink, black

What is the effect:

• The fact that Kanye West is making direct eye contact with the reader and looks like he is serious or sulky could make the readers want to read the magazine because they think this look is attractive. 
• The first part of the picture you look at are the eyes because they comply with the rule of thirds. The intensity of his gaze draws the reader in because it is as if he is looking at them. 
• The tilt of his head makes it seem cooler because he is standing as if he doesn't really care or is slightly cocky. This also fits in with the idea that he 'is rap' as the sell line next to him suggests. 

Brass - Information on rising youth bands, the latest competition results, upcoming concerts etc. 

Example of existing magazine:

• The main image is positioned behind the text
• The sell lines and masthead are on top of the main image
• The main headline is almost central so that the readers eye is drawn to it
• The main colour scheme is black, white and brown

A genre of magazine that I don't know a lot about that would be interesting to produce would be:

Celtic/folk - The newest folk artist, upcoming tours/concerts etc. 

• The main image is positioned behind the writing
• There are very few sell lines
• There is a lot of background/dead space
• There is a web address written in large writing beneath the masthead 
• There is a small accompanying image
• The main colour scheme is red, green and yellow/gold

What is the effect:
The simple colour scheme shows the fresh feel of the music it is talking about
