Warm-ups
2020, my first English book was published. It's called Harmonic Warm-Ups and it's filled with choral exercises with multiple parts, which are very easy to learn, but at the same time are fairly interesting to perform. The book can be bought for example on Alfred Publishing and Singers.com.

Conducting
In 2022, the book Harmonic Warm-Ups was published at Alfred Publishing.

Font for chord symbols
In the past years, I have often been struggling with the notation of chord symbols. If you want your chords to look good, you want the extensions in superscript and you have to find suitable signs for the flat, sharp, major seventh, diminished chord, etcetera. I have made a font which takes care of all these issues. After installing the font, you can use it in all programs, like Word or your music notation software. To create chords you simply use regular keyboard characters. See for more information MyFonts or Chord Symbols font.

Poster with conducting patterns
For conductors I made something special: a poster with the main conducting patterns. I've done my best to draw the movements for the different time signatures as beautifully as possible. The poster is quite big, 841 x 594 mm. It will look great on the wall in your study or in the classroom. The poster is 7,50 euro, but additionally there will be shipping charges. Please contact me if you like to buy the poster.

poster with kodály hand signs
A good way to learn solfege is by naming the notes of the scale as do-re-mi, etcetera. To indicate these note names there are hand signs as well. I have made a nice poster with these hand signs. A lovely item for on the wall of your study or rehearsal room. The poster is 7,50 euro, but additionally there will be shipping charges. Please contact me if you like to buy the poster.
