Have you ever listened to a song that sounds a little bit sad or emotional? Well, sometimes those songs use a special pattern of four different chords that make them sound that way. This pattern is called the i–v–vi–iv progression.
The i–v–vi–iv progression is made up of four chords that are played one after the other in a specific order. The first chord is called the "I" chord or the "tonic" chord, and it's usually the sad or emotional one. The second chord is the "V" chord, which is a little bit brighter and more energetic. The third chord is the "vi" chord, which is usually a little bit softer and more relaxing. And finally, the fourth chord is the "IV" chord, which is a little bit more stable and grounded.
So, let's imagine that you are a musician and you want to write a song that sounds a little bit sad but also a little bit hopeful. You could use the i–v–vi–iv progression to do that! You might start by playing the "I" chord, which would be your sad or emotional chord. Then you would move to the "V" chord, which would add a little bit of energy and excitement to your song. After that, you could play the "vi" chord to bring your song back down to a softer, more relaxed feeling. And finally, you could end on the "IV" chord to give your song a sense of stability and resolution.
Overall, the i–v–vi–iv progression is a really powerful tool for musicians who want to create songs that have a certain emotional vibe. It's a really simple pattern to follow, but it can create a lot of different moods and feelings depending on how you play it!
