Use Trending Music & Music that Fits the Theme
If possible, try to find trendy songs to use for your Reels. If you can’t find something that is trendy or trending, look for a song that fits well with your theme.
One of the best ways to make Reels go viral is to have music that others want to use. Having viewers click on the music in your Reels indicates to Instagram that they want to use that music as well and is viewed as engagement by Instagram.
Because of that, we usually try to avoid using original sounds on our Reels. We actually sync the song on Instagram music for a chance to be seen easier.
When you choose the song for your video, make sure you take the time to align your clips to the beat of the music. This can take some time, but it makes the video look so much better when the changes hit at the beat and not off-beat.
Something I like to do is listen to the lyrics of the song and pay attention to the pace of the song too. If the music is faster paced or more upbeat, I try to use video clips with faster motions. If it is slower paced, I slow down the clips or find clips with slower motions in them.
For the lyrics, I try to see if there is something I can use to line the lyrics up with the images or video clips. For example, on this recent Reel I posted, I matched up the lyrics to the videos.
It says in the sound, “Life moves pretty fast,” so I use a lot of quick clips with movement in them. Then when the voice says, “If you don’t stop and look around once in a while…”, I used a clip of me stopping and turning to look at the camera. Some people may not notice these little things consciously, but it can be what sets my Reels apart and helps them perform better.
Because editing Reels on Instagram can be difficult, I like to screen record the songs or sounds I want to use from Instagram. I can extract the audio in InShot so that I can edit my Reels to the beat and line up clips with specific words in the audio. It makes it so much easier than trying to go back and forth between InShot and Instagram or trying to just edit it all in Instagram.
