Most people who use garageband usually mess around a lot but it can actually be used seriously and you can make amazing stuff. Before you start jamming out though you might want to download all of the sound packs because then you have more live loops and alchemy synth sounds.
I think one of the best features is the sampler keyboard because if you want to make a song but you don’t have that sound effect or little melody you want then you can record it and sample it. It works great but make sure that there is no background noise. One day I wanted to sample saria’s song from the Legend of Zelda Ocarina of Time but my brother was screaming in the background the recording got ruined. Here are some sound effects to get started. https://www.youtube.com/watch?v=wOFVrjL-XBM and https://www.youtube.com/watch?v=B-uIfFgMPyw
Another cool feature I want to talk about is the alchemy synth and live loops. With the Alchemy synth you can choose from a bunch of keyboard sounds and lets you play the sound you chose on a virtual piano to make music. The live loops are sounds that have been made by apple that you can put in your songs but if you find a green live loop then you can find an alchemy synth sound and the live loop to be played as that sound.
Now I will tell you how I made my song festival.I started by choosing the live loop festival mallets and put it into the song. Then I found Festival kick for the beat of the song and added a latin pop drum loop. For the buildup to the drop I just found a snare buildup live loop and all that was left was the drop. For the drop I made a separate instrument that was the hammered piano sound from the alchemy synth and then I dragged the festival mallets loop from before to make it sound like how it is.
