Now about reading music...(and please excuse me if you are a sight-reader, because today will all seem very patronizing I suppose) - I am an awful music notation reader. For me to sight-read "Fur Elise" would result in a 3 hour rendition ("sight-read" of course means play the piece from looking at score and not from memory). Also my "internal voice" - that is, reading a score and hearing the music in my head without an instrument or singing - is about as accurate as the 10th person's recitation in a game of "telephone".
However with just a bit of practice and a healthy serving of patience, any non-musician can appreciate these score videos I think. Just a basic understanding of music notation should help quite a bit. Now I'm not qualified to give a lesson on reading music (see the link at bottom for that), but here's some pointers which helped me...
Look at the black dots and don't worry as much about the vertical lines attached to them. The dots tell you the direction of the pitches.
OK - now look at the vertical lines. The more lines attached to a note the shorter the note is going to be. Shorter means it will go by faster.
The time signature for this one is 2/4. That means it's an even rhythm and can be counted in 4's: 1-2-3-4-1-2-3-4....
Other even rhythms are 4/4, 2/2, etc...if you see a big "cents" sign in the beginning (or "C") then that means it's countable in 4's.
If the time signature has a top number that's a multiple of 3 (3/4, 6/8, 12/8, etc) that means it can be counted in 3s: 1-2-3-1-2-3...
What helps me alot is to either count under my breath, tap my foot, or "conduct" with my hand as the measures go by. That way, even tho I may be confused by a measure (bar) at least I'll still be on the right bar later on. Never stop.
Conducting 4's (simple meter):
Conducting 3's (triple, or compound meter):
If a piece is a fast one, then I usually count in 2's (down-up-down-up...). If it's a really slow one, you can count to 4 twice in 1 measure/bar.
If you get lost then the wonderful thing about these videos is that when the picture changes at least you're caught up! Just start reading and matching what you hear with what you see right then. Believe me, there's nothing more embarrassing then flipping back and forth through a score book trying to figure out where the performance is at :). These score-following videos prevent you from missing a repeat sign and all that.
Following a score with music is great because
1.- You'll see things which you might not be aware of when just listening. These include melodic patterns, subtle changes in note articulation...crescendo, sforzando and other dynamic markings, etc...
2. You'll be interacting with the music as opposed to being a passive observer. It's kind of like a game - your eyes must follow along an invisible bouncing ball. The problem with "passive" listening is that it leads to "attention drift" and "background music-itis". Beethoven's music works remarkably well in setting a mood (and some of his stage music is intended for just that), but to really get the absolute most mileage out of his pieces, they can be experienced like reading a book, or watching a movie - or better yet, carrying on a conversation.
3. It's fun and gets easier the more you do it.
Here's an early Beethoven piano sonata to get started:
Piano Sonata #2, Op. 2 No. 2 in A major 2nd Mov.
And Piano Sonata #10, Op.14 No.2, 1st Mov.:
OK the below link will take you to a playlist (which I will try to keep updated) listing every score-following video of Beethoven's piano sonatas on Youtube. Many of these performances are not by "professionals" so don't expect Glenn Gould or Vladimir Horowitz, but they are great for exploring the works themselves.
Piano Sonatas w score:
Piano Sonatas 1-6, 7, 8 ("Pathetique"), 9, 10, 17.3 ("Tempest"),
18.2/4 ("The Hunt"), 27, 28, 29 ("Hammerklavier"), 31
Of course there's no reason to feel any pressure to follow with the score, it just makes listening to Beethoven's piano works a different experience.
Here's what looks to be a good site on learning how to read music (I can't guarantee anything tho - maybe I'll add more sites later):
Personally, I highly recommend this book: "Learn to Read Music" (Shanet)
