I saw this piece of street art earlier today. It features some good advice from W. B. Yeats…which can apply equally to musicians.
The first half of the quote tells us that to learn our trade, it pays to sing whatever is well made (i.e. as a musician – the stuff to which you enjoy listening, the stuff which you would like to be able to play).
Sing it, play it, learn the chords, the melody, the phrasing, the solos you like, improvise over it yourself. The more you do of this, the more you will find yourself taking what you like, leaving what you don’t like, and hence forming your own playing/singing style.
I don’t think the word ‘not’ should be there on Line 3 – hence it should read ‘Scorn the sort now growing up all out of shape from toe to top’. Here Yeats is disparaging of some more modern poetry, and is discouraging young poets from learning from these.
Again likewise as a musician, if you don’t like something, then don’t play it, don’t learn it, and then the chances of it getting into your playing are nil. Whatever you think is well made though, eat it up!
