Practise 01:

The methods in which I practise my pieces are written within this post, however beforehand I would usually warm up:

For guitar:
>Play chromatic scales in order to stretch fingers and prepare for faster playing when practising. A better way to practise this is to start slow and use a metronome to gradually speed your playing up and therefore again prepare your fingers for perhaps fast runs, licks or scales. Play these starting on different frets and continue them across different strings, ascending and descending.

For Vocals:
>Sing scales starting in your low range and ascending across first of all 2 octaves until your reach your higher register. Depending on what you are singing, you may want to do the same with chest voice as you do falsetto. Remember to use different vowel every 3 scales. Doing this before practising or performing can relax your voice and make it more comfortable with the notes at the ages of your range yet at the same time increase your range as your try to sing higher and lower every over time. However it is important not to strain and potentially lose your voice by doing this warm up. Depending on the piece I am practising determines the key in which I sing some scales.

Practising:

A normal practise for me would usually last an hour. I schedule my practise by prioritising by doing techniques first and learning songs second. By scheduling your practise, I maximise the efficiency of the time set in which makes it easier to achieve my set goals.
For 25 minutes (after warming up for 5) I practise individual guitar techniques such as, sweeps, scales and perhaps learn another chords shape and apply it to a progression in order to consolidate its uses for my musical benefit.
For the rest of the practise (30 Min's) I work on my pieces I have set to perform in which are written in the previous posts with a 5 minute break in between. I do this for this length of time to ensure I rehearse the pieces set well.
