This is a fascinating video, showing the almost hypnotic process of engraving music by hand. It's something of a dying art, with software such as Sibelius and LilyPond improving all the time in their ability to recreate the work of these craftsmen. There's a certain irony to this, in that the layout and style of engraved music itself recreates manuscripts, in the swirls of the treble clef, the angled lines of sharps, and the diagonal shape of note heads.
Some of my pupils must be sick of hearing me ask this recently...
Here's a different question: what does a key signature tell us? "It tells us what key a piece is in", or "It tells us what our key note is". Right? Well, yes and no. Each key signature corresponds to one major and one minor key, that much is correct.
When working at shifts from third position, it's really important to be able to hear which note you're aiming for in your head, before moving. Otherwise, it's a bit of a stab in the dark!
One way to help is to think of familiar tunes which use the interval you're shifting across, so I've put together this guide to help you. Do take your time with this: it's better to go slow and to be confident about what note you're aiming for, rather than rushing it and hoping for the best.
"LilyPond came about when two musicians wanted to go beyond the soulless look of computer-printed sheet music. Musicians prefer reading beautiful music, so why couldn’t programmers write software to produce elegant printed parts? The result is a system which frees musicians from the details of layout, allowing them to focus on making music. LilyPond works with them to create publication-quality parts, crafted in the best traditions of classical music engraving."
