Christmas Classics Keyboard Skills Volume 1 from Musical Contexts contains treble clef melody line arrangements of 10 well-known Christmas Songs.
 
Each song is presented in four differentiated ways: (see sample image)
treble clef single line staff notation and chords and lyrics
treble clef single line staff notation with fingering and chords and lyrics
treble clef single line staff notation with note names and chords and lyrics
treble clef single line staff notation with fingering, note names and chords and lyrics
 
The most complex Key Signatures within volumes 1 and 2 are two sharps and one flat and the arrangements use Simple Time Signatures, several with anacrusis starts/upbeats.  Each song contains dynamic markings, some with changes in dynamics, and a tempo or performance direction to encourage effective performance technique.
 
Chords can be used as a Stretch and Challenge task and performed either as triads, using the "single finger" chord function found on several keyboards or on guitars or ukuleles, or any other suitable instrument as an accompaniment.
 
Christmas Classics Keyboard Skills Volumes 1 and 2 are flexible, practical and invaluable Christmas music resources that can be used year after year.  You could include arrangements within a "Keyboard Skills" unit, set one or more arrangements as practical Christmas keyboard cover work, or use arrangements as part of a "Christmas Keyboard Challenge" over one or more music lessons on the busy approach to Christmas.  
 
Christmas Classics Keyboard Skills Volume 1 contains 40 scores and is available to download upon purchase as a ZIP file containing the separate Christmas Song arrangements as .pdf files: ideal for 'print, play and go!'
