Those are triplets, which means you have to fit 3 notes in a time where you would normally have two without altering the overall duration of the group.
>.<
I’m going to memorize this by remembering a three at the bottom of the row and that it’s slightly arched. Merci outin.
Trying to count 3 beats for a 6/8 bar usually won't feel right. 6/8 looks the same as 3/4 in terms of how many eighth notes fill a measure, but they feel very different. In 6/8 each measure actually has 2 main beats. Each of those beats can be divided into groups of 3 eighth notes. In 3/4 each measure has 3 main beats which can be divided into groups of 2 eighth notes.
For slow practice and learning the rhythm it is good to count the 6/8 as 6 beats: ONE two three FOUR five six ONE two three FOUR five six. When you understand the rhythm and play it up to speed you might think of it as just two beats: ONE and uh TWO and uh ONE and uh TWO and uh. Or something like that.
For now I’ll practice counting, 1, 2, 3, 4, 5, 6 and using the and/uh when I can’t get through it. I got the general concept down thanks to you and mikeowski (and my teacher). I hope I can apply it when practicing. I’m going to go really slow at first.
Yes thats correct, the moonlight sonata has the right hand playing in triplets (the -3- under the first two groups shows this, aswell as the grouping in 3 notes in all the following ones), where you must count 3 eigths in a beat instead of two.
Triplets must be counted like this:
Ta-ta-ta
Ta-ta-ta
Ta-ta-ta
instead of
Ta-ta
Ta-ta
Ta-ta
Also rhythms which are in 8ths, like 3/8, 6/8 or 9/8 need to be counted in 3 (like the triplets) aswell.
Here is another visualisation:

But sir, you just said and showed me to count 1 to 6 with the other example.
Not to discourage, but why are you learning that particular arrangement? You seem like you're extremely passionate about piano, enough so that you would much rather be playing the real thing.. ..and so perhaps delaying the moonlight if you're not yet ready, or just putting in the effort to learn whole enchilada anyway?
..I wonder why the guy wrote it in 2/4 rather than cut common?
Halfway through this arrangement I stopped learning it and tried learning the real thing. When I brought it up to my teacher he said to first finish this arrangement and afterwards we could go for the real thing.
Technically I can already play the first page of the real thing, but I haven’t touched it since my teacher told me to wait.
You are correct though, I’d rather play the real thing, but I’m learning the last few measures of the arrangement and am almost done.
I’ll tackle the real thing down after the Mozart piece, most likely and hopefully.
Your words remain encouraging, thank you sir.
I think I'm with you now. I was confused by your meaning, because if you take out seconds, then it just is what it is in the first place. It's simply saying what the notes actually mean- not interpreting at all. However, I then realised that it might be an issue of translation from the American names? Sorry to Americans, but this whole "quarter note" nonsense really adds pointless complexity. In regular time, crotchets are 1 quavers are half and semiquavers are the "quarter note" (not in reference to this silly terminology but in reference to proportions of beats- why base the terminology on a quarter of a note that rarely if ever counts as a beat, rather than as 4 beats?). This is the default for most music. I think this way as the norm anyway, but presumably you were making the translation from the complexity of the American system to this simpler ratio, rather than worrying about actual literal seconds in time?
Also, the thing about feeling rhythm is that you always start from beats rather than details. It should feel more strange to change time signature than to maintain- so I suspect that you are thinking too much in small details. First think in 4 definitive beats per bar and count them. Then add detail around them. It should feel really odd to cut a bar a single beat short, if you are internally feeling the character of each beat.
My teacher is from Germany and has done music school (conservatorium).
My first teacher was Lypur, from youtube.
https://www.youtube.com/user/LypurHe taught me the values of each note. I’ve only had about 2 hours of lesson from him with the help of his youtube vidoes. I learned mary had a little lamb from him.
My teacher has yet to deviate from Lypur’s counting method, so I’m not sure what the American system really is. I just learn what my teacher teaches me.
But isn’t a quarter note, just that? A quarter of a bar, a quarter of the 4/4 time? A half note is 2/4 of that and so not.
Could you explain it more so I can understand perhaps?
I think the reason Ranniks is so confused is that he has jumped straight into relatively complex pieces (for someone who has no musical background) without going through the basics first.
Correct.
