The five things i would put in my studio are a microphone , head set to hear myself and to hear what ive made. I would also have cables because it would plug things together. I would also have a small mixing pad to make a beat for my songs. I would also get a Audio interface because it has the primary purpose of providing all the necessary connections to send your music into the computer when recording and out the computer during playback.
The music i would make would be more pop than anything but i don’t have a certain music type i would make , i would hopefully make all kinds.
