Good sightreading skills help us to process key information about a piece quickly and efficiently, giving us an overview of the musical tasks that lie ahead. Armed with four simple strategies and only a few minutes of sightreading practice per day, you can learn to think and play your way to greater sightreading success than you've ever had before. It's important to subdivide any syncopations, tie-overs and dotted rhythms. Mentally count out a full measure before you start, breathing in the tempo you will play. It is pointless to worry about missed notes.
Concentration is the key.
Allow yourself the luxury of a mistake or two, but try not to stop. If you stumble badly, a slower tempo might be in order. Go back later to work out the problem spots. Your band director or private teacher can suggest a collection of pieces that will be fun for you to play. Try the technique on all of your music.
