Is there any downside of doing something like 10min@threshold and 10 min easy rather than 10 minutes at threshold and 5 minutes easy. Would too much rest just be unnecessary or would it actually have a negative/less optimal effect.
Hi, I'm trying to memorize the sound, names and the half-steps needed for each interval. However, it looks like each one has an augmented/diminished version. Does those intervals sound exactly the same? I don't understand why and how a perfect unison is called a diminished second and how would it sound different. Does that mean each interval has two sounds and I should understand and memorize the augmented/diminished version?
Hi,
Very new to ESPHome, esp32/esp8266 modules and YAML. I wanted to build an air quality sensor that I could connect to my Home Assistant hub. I was able to wire it up and using the YAML below, it reports values back to HA.
The thing is, the SDS011 sensor has a mean lifetime of 8000 hrs, and I've seen multiple posts from people recommending only have the sensor scan intermittenly in order to preserve the life of it. I cannot figure out how to do that though. I tried to set an update_interval under the sensor, and it reports this time in the log, but it is ignoring it. I am getting data every 1s in HA and the fan on the sensor is always spun up.
Any ideas or suggestions greatly appreciated!
Thanks

I'm currently learning about intervals but have found the naming conventions... confusing, to say the least. There seems to be no consensus on why perfect intervals are perfect and the others aren't besides "history", which, OK. But if it's just a historical convention, why don't perfect intervals have a quality two steps down? And why isn't there a quality for either interval type that goes two steps up?
I've had 3 videos uploaded for a while now. I just recently re watched them to find out that at certain points throughout the videos the quality would drop drastically to the point where you would see actual pixels, but only for about 2-3 seconds. I then watched the video files themselves through my computer to see the problem isn't there. I am completely lost and I would love if somebody could give me an answer to this issue. Thanks in advance!
Why doesn't the second interval in the diatonic scales have a perfect quality?
I've been trying to learn music theory and I thought I understood the reasoning behind the interval quality naming conventions but after realizing the following I'm just confused. Any help would be much appreciated.
Given the major scale formula: R, W, W, H, W, W, W, H and natural minor scale formula: R, W, H, W, W, H, W, H I though that 4th and 5th intervals were considered "perfect" because the fifth from the root in both formulas required the same amount of half steps. Also the major and minor thirds follow the scale pattern as well. However following this same logic, it falls apart when you get to minor and major 2nds because the 2nd from the root in both scales is the same number of half steps away and I would think that 2nds should also be "perfect", but this is not the case. So now I am confused as to the origin of the interval qualities as I thought they were based on the major and minor scales but they seem to slightly unrelated.
I'm starting to be able to identify harmonies more complex than just 7th chords, not asking for every single chord but some examples would be nice. Thanks in advance and happy new years.
