Eventually, practise will make it an automatic process for you to see a note on the stave and play the correct pitch on your instrument.
Until then, you need an accurate way of finding the note names on the stave so that you can then find the right pitch on your instrument. If your way of finding notes is quick, that will help you to make a fluent melody, rather than a disjointed series of notes.

Notes appear on the stave in a logical order. An order which even young students know: As we go up the stave … A, B, C, D, E, F, G, A, B, C, D, E, F, G, A … As long as we know where A is on the stave, we can easily work out what any other line or space is. We just need one secure “Landmark” note on each clef we use, and can find notes from there.

An alternative method that you may have come across is to use mnemonics, such as “Every Good Boy Deserves Football” to remember the notes on a stave’s lines or spaces. This has a number of disadvantages:
1. You need to remember the Mnemonics accurately, a feat in itself for a young student
2. You need to remember which one is for lines and which for spaces. And pianists need to know which are for Treble Clef and Which for Bass Clef.
3. You lose the simple principle of notes being in alphabetical order. They are now in the random – sounding sequence such as G, B, D, F, A.

Memorising one or two landmark notes on each clef is much easier and faster than trying to memorise mnemonics, and remember which one is for which clef, and which for lines or spaces. We prefer to use the landmark notes method.
Please do not confuse your child by using mnemonics with them at home. Get them to explain to you the method that they have been taught by us. If they can not yet do so, the landmark notes might need a reminder from us. Thank you very much.
