I've been playing with some different dividers in my dandelion delay plug, trying to get some more interesting 'rhythms' going. I've found using dotted (i think...) timings pretty cool (obviously... 🙂) but am getting confused over terminology and, well, what exactly I'm actually doing ('formal' music training non-existant, i do it all by ear...)

I guess i'm extracting the crotchet value (60/tempo) then dividing that down. Where i have been, for example, dividing by 8 and labelling that 1/8, i'm now finding a divisor of 1.333' (0.75 of the crotchet value) being referred to as a dotted eigth which goes against how i thought things should be...

So, anyone a decent resource where i can get my head around these concepts? A table of common times, dividers, correct names etc. would be good. 🙂

cheers, .g

First... to give you a clue as to my limited knowledge on the subject, I was not familiar with 'crotchet' for beat value.

A dotted eight is 1/8 + 1/16 or 3/16. The dotted values are 50% longer than their un-dotted counterparts.

So if the crotchet is a quarter then a dotted eighth should be 75% as long.

P.S. - a quick search turned up this site: http://www.treblis.com/Notation/Music.htm

Seems OK to me.

Thanks Oddson, that's helpful.

I think i'm getting confused about whole and quarter notes: a whole note at 120bpm is a delay of 2000ms. So what I think of as whole notes are actually quarters... I guess that's what the bottom '4' in 4/4 means... 🙂

Onwards and upwards, .g

120 bpm actually means 120 crotchets per minute. In terms of time you will have

1 breve = 8 crotchets = 4 seconds 1 dotted semi-breve = 6 crotchets = 3 seconds 1 semi-breve = 4 crotchets = 2 seconds 1 dotted minim = 3 crotchets = 1.5 seconds 1 minim = 2 crotchets = 1 second 1 dotted crotchet = 1.5 crotchets = 0.75 seconds 1 crotchet = 1 crotchet = 0.5 seconds 1 dotted quaver = 3/4 crotchet = 0.375 seconds 1 quaver = 1/2 crotchet = 0.25 seconds 1 dotted semi-quaver = 3/8 crotchet = 0.1875 seconds 1 semi-quaver = 1/4 crotchet = 0.125 seconds 1 dotted semi-demi-quaver = 3/16 crotchet = 0.1875 seconds 1 semi-demi-quaver = 1/8 crotchet = 0.0625 seconds 1 dotted hemi-demi-demi-quaver = 3/32 crotchet = 0.046875 seconds 1 hemi-semi-demi-quaver = 1/16 crotchet = 0.03125 seconds

Hope that helps a bit. If not then it was a memory exercise for me so it's all good 🙂 Sorry if I kinda repeated what somebody else said, it's just I'm trying to get back on top of my music theory again and it's good practice to dig out the stuff at the back of your memory.

Thanks Mike,

Forgive me if I don't commit that list to memory myself... 😕 😀

It is helpful though, I think I've got the timings correct now, just need to confirm i've labelled them correctly.

cheers, gary.

Haha, well I did have to use a calculator for the timings, but I remember all of the note names/values. That's what forced piano lessons up to grade 5 theory does for ya! 😉 I don't hate them for it.

Oh, by the way, I'm not sure if American terminology is the same as here in the UK. Well, the UK uses Italian wording for musical terms, but I think Americans tend to use terms like 'whole note' instead of crotchet? Correct me if I'm wrong. It depends whether you want to stick with your roots or conform to the American way of doing things. I have had to start using spellings like 'color' instead of 'colour' because it's required for many programming languages like html & css. Am I bi-lingual?

GaryG ·

ooh, don't get me started on HTML... the hours I wasted wondering why I couldn't 'centre' anything... 😉
