Here’s a handy rule of thumb: a four-key piano will have an 8-note octave-scale
A seven-key piano has 12 notes: 4, 5, 6, 7, 8
and a eight-key piano, if I’m remembering that right, can have a 17 note range.
This might also be helpful at a glance for when you’re going to put together a playlist on Spotify.
The next time you’re browsing your library, or your favourite station, you might be able to make some pretty neat conclusions.
For instance, the song on Radio 1 might only play a few bars, and it might only come on at a particular time of the day.
It might also come on at a certain time of the week.
You might then realise that, in order to keep the song’s rhythm, when you listen to it in the evening, you might need to listen only at certain times of the day, in order for the radio to be playing at the same time of the day.
Of course, this only works, and is very unlikely to be used, on a regular basis.
But it might be helpful to think about it, and remember that some artists use different keys in all these different times of the day.
It might also be a useful point of reference when you’re trying to decide between all these different artists, whether you’re listening to one or all of them.
So, how quickly can I see how much there is to buy?
While shopping for your next purchase, and while browsing online, look for similar items, that are close in price to each other.
For instance, you might be willing to be a little bit late, and buy some shoes you’ve seen in Ebay. If you get there a few minutes later then buy them both.
You might also be tempted to buy your favourite shirt and only use it for the very first or very second pair of shoes you’re going to buy (or you’ll only be wearing it for two days anyway). There might also be other items within these price points that are similar in price.
Of course, if you’re shopping for more than one item it’s not always easy to know how much money to spend based on their price, or you might get a mixed bag of cheaper options.
So you might be in a position to buy several things that you might not typically buy, just for
