As an instructional author, Ryan has published original books on
bass drum technique,
drum and bass breakbeats,
drum rudiments,
thrash metal drumming, and
subdivision and music reading. He has also transcribed two 19th century manuals into modern notation, translated Swiss and French military manuals into English, and reissued editions of multiple public domain drum books. The first book was
Double Bass Drumming Explained: A Comprehensive Reference on the Art and Science of Double Bass, in 2012, which discusses double
bass drum technique, style, and theory. The book draws on Ryan's own critically acclaimed drumming techniques and his teaching experience. Ryan published his second book,
Double Bass Drumming Explained Part 2: The Workbook in 2013. Where the first book was mostly text, this sequel is a traditional instructional method consisting of mainly beats and notated exercises for practice. In 2016, Ryan published a combined and revised edition of his books called
The Complete Double Bass Drumming Explained. This edition fixed minor errors and added new topics, notably a section on cam shape, while condensing the previous two books into a single volume. In April 2017,
The Complete Double Bass Drumming Explained was picked up by publisher
Hudson Music and re-released in an exclusive digital ebook format. In March 2018, Ryan secured a second deal with Hudson Music for the publication of his book,
Live Drum & Bass - Breakbeats and Electronic Music for Real Drummers. This was Ryan's first offering outside of double bass instruction. In 2019, Bloom published two books. The initial publication was his third book with publisher Hudson Music called
Encyclopedia Rudimentia - The Ultimate Drum Rudiment Collection. Encompassing over 850
Drum rudiments, this book diverges from his earlier works for drum set by compiling basic rudimental snare exercises from different cultures and traditions including
Drum Corps International hybrid rudiments, Ancient
Fife and drum corps rudiments, and European military rudiments alongside the
Percussive Arts Society and
National Association of Rudimental Drummers standards. Later, he published his first work of non-fiction outside of music entirely, called
The Forgotten Side of Bandelier, which deals with the archeology and anthropology of the
Tsankawi section of
Bandelier National Monument. In 2020, Bloom also published two books. The first, an edition of
Charles Stewart Ashworth's 1812
Fife and Drum manual,
A New, Useful, and Complete System of Drum Beating that updated the 19th century notation to 21st century standard drum music, was published in January. The second book was a method called
Thrash Metal Drumming that detailed the types of beats and fills used in classic and modern
thrash metal. It was published by
Hudson Music on October 28. Bloom again published two books in 2021. In April, he released an edition of
Samuel Potter's 1817 drum manual
The Art of Beating the Drum that updated the ambiguous 19th century notation to modern percussion music. In June, he announced that Hudson would be releasing a book called
Subdivide and Conquer, in collaboration with author Robert W. Miller, a method for counting and reading rhythms. In 2022, Bloom published an English translation of the
Swiss military's World War I drum manual
Tambour-Ordonnanz für die Schweizerische Infanterie 1917, which had only previously been available in French and German. He also contributed an article to
Percussive Notes called "The Inverted Flam Tap: a Multinational History". Bloom published two books in 2023. In February he released an English translation of 's 1885 rudimental manual
Méthode de Tambour and in March
Rudimental Grand Tour was released, his first book with publisher
Mel Bay. In 2024, Bloom published three books. In January, an annotated re-printing of
The Moeller Book, by
Sanford A. Moeller, based on the first edition from 1925, followed by a July release of
Italian Rudimental Drumming, an original publication that describes the historic military drumming tradition of the
Kingdom of Italy. He further published an annotated re-printing of Fred Poole's early 20th century manual
Side Drum Tutor in November. In 2025, Bloom released
A Field Guide to 50 Drum Rudiments with co-author James A. Musser on the imprint Ruffe Dragg Press. ==Education==
