Make up a weekly practice timetable for both of your chosen instruments. A daily practice session of 15 - 30 minutes is recommended.
Set targets and keep a progress diary to track improvements. Difficult areas of the music may require a more disciplined approach – allow yourself several days to practice tricky areas more slowly, aiming to play a little faster by the end of the week.
Keep practice sessions interesting by working on more than one piece and by trying to play a variety of musical styles. For example mixing jazz and classical or blues and baroque will give you more variety and help keep you concentrating.
If you miss a day, try to extend your next practice session by 5-10 minutes
Before you practice:
check your instrument is in tune (if appropriate)
do some warm-up exercises on your instrument/voice
consider the posture and technique required - this will help improve tone
When you practice:
record yourself practising so that you can listen back and reflect
break difficult sections into small chunks
practise slowly and repeatedly, then gradually build up the tempo
practise in front of other people to help build confidence
practise scales and studies regularly to improve technical ability
After your practice, reflect on it by:
listening to or watch recording of yourself playing
identifying areas that may require further practice
noting the progress you see in your practice sessions in a notebook, or a logbook provided by your teacher
Remember you can learn from working with and listening to other musicians as well as from concentrating on your own practice
