Piano practice is an important aspect of piano playing. Piano pedagogues have several theories on the best way to implement and encourage students to practice. Resources are available for students to chart the time spent in practicing. Some teachers award stickers and other incentives depending on the age of the student. Teachers dictate varying amounts of time required for students of different levels of skill. For example, a beginning student may be required to practice 20 minutes a day while an advanced student may practice over an hour a day. A common approach in a practice session is: 1) warm-up - scales, arpeggios, chord progressions; 2) work sections of pieces gradually expanding to include before and after the trouble spot - rhythms, fingerings, and/or notes that need to be drilled; 3) work entire pieces - consistent tempo, accurate dynamics and touch, etc. The metronome is a useful tool in piano practice sessions. Students need to have ready access to their own piano - having to travel somewhere to practice often provides an unnecessary hurdle for students.
