These animated videos provide a simple musical context that will allow the christian student to learn, sing, and play along with a paraphrased version of some Lord’s Days from the Heidelberg Catechism.

The versification and improvisations are provided by Aart Blokhuis, from Burlington, Ontario with melodies that are based on familiar Genevan Psalter tunes. Though there are only 9 samples shown here, it is hoped that Lord willing, many more will be made available.

The made up word “Ref-Grass” is a play on the word Bluegrass which is a type of traditional country music that is influenced by jazz and blues.

Ref-Grass is also meant to be music that is influenced by traditional christian music and played on simple contemporary instruments at home, around the campfire, or as many Christians do, in hiding.

The animations are optimized for use on a smart phone.

Hymn 67

This is a sampling of the congregational singing of Hymn 67 Come Lord Jesus Maranatha. (Canadian Reformed Church Smithville 2017)

The text for Hymn 67 in the Canadian Reformed Book of Praise – Come Lord Jesus Maranatha was co-authored by William Helder and William W.J. VanOene, 1979/2009

John Goss composed the melody for LAUDA ANIMA (Latin for the opening words of Psalm 103) for this text in 1868. (It is in the public domain)

Along with his original harmonizations, intended to interpret the different stanzas, the tune was also included in the appendix to Robert Brown¬ Borthwick’s Supplemental Hymn and Tune Book (1869).
LAUDA ANIMA is one of the finest tunes that arose out of the Victorian era.
A reviewer in The Musical Times, June 1869, said, “It is at once the most beautiful and dignified hymn tune which has lately come under our notice.”



Leaf and Blade

It was a very cold day in December 2018 and Pastor Edwar Dethan visited us briefly at home to teach me a song he had written and that he wanted some accompaniment for at his mission presentation slated later that week, here in Lincoln ON.

Coming in from Timor Indonesia and not being used to our climate he was still stiff and shivering as he quickly picked up a freezing borrowed guitar and could hardly play a note.

None the less he left us with a very wonderful little song based on Lord’s Day 10 from the Heidelberg Catechism that nearly anyone can learn to play.

Now as we live at a time when many are looking for things to teach or do with their stay at home children I thought this might be of interest to some.

For an interesting variation play the D and Em chords in the 5th and 7th position.

Now do you see ….how nothing comes by chance?


My wife and I took a small hike at Ball’s Falls In Vineland Ont, to the Upper Falls on March 24-2020.

We were impatient for spring and looking for some sign of it in the form of buds or leaves or anything!

Like everyone else we were impatient for the COVID 19 quarantine to end, but unlike many, we had a beautiful isolated place that we could go to and avoid any potentially dangerous contact with anyone.

This is a small video clip of our tiny trek with some background music in the form of Psalm 84.

” LORD, one day in your dwelling place is better than a thousand days outside the courts of your salvation.” has a little more poetic & practical poignancy today.


This past summer we had an extended family camping at a local park. I used a GoPro camera to capture one of our camp fires as the evening fell.

Today is March 21, 2020 and it seems as though the world has changed completely. As I work and live in isolation, safely in a warm home, I count my many blessings and remember many fond memories of the past.

We are currently witnessing the outbreak of what appears to be a world wide Virus (COVID-19) outbreak.

Time will tell how this event will turn large or small but I know the One that turns all events.
