One of the best things I've accomplished over the years is the development of a comprehensive process for teaching students to play well in every major key.  An overview of the whole process can be found in my master's project.  That document can be downloaded from the ERIC database by clicking the ERIC link below.   Have a look and use it if it suits you. 


The heart of that process is carefully selected performance repetoire.  I also use the following instructional materials:


The set is available in a single, reproducible book.  A copy of the book, along with permission to make copies for a single band program is available for $50.00.  The book includes the following chorales:

Key C F Bb Eb Ab Db

Chorale Just A Closer Walk With Thee Rhosymedre Brightly Beams Our Father's Mercy More Holiness Give Me I Know of A Name What A Friend We Have in Jesus

Key Gb B E A D G

Chorale Guide Oh Thou Great Jehovah Sweet Hour of Prayer Panis Angelicus All Glory, Laud and Honor Breath of Life Nearer My God to Thee

The B flat chorale - Brightly Beams our Father's Mercy and E flat chorale - More Holiness Give Me are available for free, along with a bonus Bb version of Just A Closer Walk with Thee.  Click the link in the left panel to download them.  Each chorale is designed to be copied back to back on a single sheet for the whole band.  A full score version is included for the director.  They're enjoyable to play, handy as warm-ups, and teach key centers in an engaging way.  Enjoy!
