Scientists have different claims in this area. Probably due to lobbyism and capitalism in general, but there are a few factors we should look for when considering to listening to music while sleeping. The rhythm actually make the biggest impact, but in different ways! The beat of the song should be in a low “BPM” while it also has to be tight. A song with off-beat drums can mess up your sleep worse than the cats outside Frank and Charlie’s window.
Genre < Rhythm
When sleeping to music, it doesn’t really matter which genre you are listening to. There’s no master music genre for sleeping with music, they all are subjective.
You should focus on finding a song that you like, preferably in a genre that you usually listen to. However, it is important that you are listening to music with a low “BPM”, an abbreviation for Beats Per Minute. So rather than putting on DragonForce – Through the Fire and Flames because you like electric guitar, try to find another song with electric guitar such as Eric Clapton – Tears in Heaven.
The main focus should be placed on finding music with a good rhythm rather than playing random songs on a playlist. The hearts of humans normally have a BPM around 60-100, but athlete hearts can have as low as 40-60 BPM while resting. So try to evaluate yourself and your shape, find a song in a low BPM and try to stay under 60 BPM.
There are actually sites that provide the correct BPM for any song. The BPM is defined by the rhythm of any song, but many sites seem to be doubling up the BPM so if you choose to use a site to find out the BPM for a song – you should make sure that they are using correct metrics.
60bpm is the same tempo as 120bpm & 240bpm; a song might be listed as 120bpm while it actually has 60bpm.
This site is probably the best to use, provided that you have some-what rhythm skills: http://www.tempotap.com/
Good for falling asleep
Some argue that music can do wonders for sleepers while others say that sleeping to music or not makes no difference at all.
The fact is, that it’s usually easier to fall asleep to music while sleeping to music can be dangerous for the sleeping quality. I personally think that sleeping with music can be a great contribution for anyone if set up correctly.
You need to make sure that all songs in the playlist has approximately the same beat, preferably somewhere around 40-70 so that your heart easily can keep beating in “resting mode”.
Also, try to avoid listening to songs with an unnecessary amount of lyrics. Lyrics can trigger your mind to think about stuff while dreaming. It can ruin a perfectly good sleep in other words.
Apart from listening to certain rhythms, it’s equally or more important to only listen to tight rhythms. You are very likely to wake up during the night or just have shitty sleep if you are listening to songs with off-beat drums.
This scenario can take place even if “only” the bass or guitar is slightly off beat. So, don’t put all your eggs in one basket by only focusing on finding songs at a specific BPM – also make sure that the instruments in each song are being played tight.
Hip hop usually have slightly off-beat drums, same goes for some pop music as pop try to pinch a bit from the semi-off-beats that can be found in new hip hop. Jazz also has a tendency to play slightly off-beat in many songs.
Soft Natural Music
Try to avoid “hard” instruments. I don’t know if this is a recognized way to phrase it but I’ve chosen to use it anyway.
The electric guitar usually has a hard sound and same thing can apply to the steel stringed guitar in some cases. Heavy drums and violin can also be considered too hard but not in all cases.
So what you should try to do is to find natural music with as little instruments as possible. Bird sounds, soft pouring water, blowing winds and low whistles are great tunes to listen to.
But please remember to make sure that the rhythm never exceeds 80bpm. Listening to music while sleeping is lovely if you find your own favourite but keep in mind that only one thing is constant – change.
Try to mix up your sleeping songs every now and then as different tunes can help you remember and create new dreams during your REM periods overnight.
White noise is a concept for levelling out unwanted sounds. Charlie and Frank for example, have lots of screaming cats outside their window but they can compensate the bad noise with slow classical music or soft natural music.
Let’s say that the cats outside make a noise of 60 decibels, so Charlie could level it out by playing slow music (40-70bpm) at 55-65 decibel.
Using white noise can be hundreds of percent better than asking your neighbour to turn down the music.
Although, if your neighbours are a reoccurring problem – consider making your place soundproof as you still risk the chance of background music interfering with the music from your white noise.
The cats I’ve had in my life usually appreciated music as a way to fall asleep, or I bored them by playing, not sure.
The Mozart Effect
Music is clearly linked to spatial reasoning, which are other words for imagining opportunities which haven’t happened yet; Understanding of Possibilities.
