Krissy Keech

Piano, Musicianship, Theory, Improvisation

Dr. Krissy Keech is passionate about piano, pedagogy and practising!  

She completed her PhD in Music Education at McGill University, where she focussed her doctoral research on elements of piano pedagogy and teacher effectiveness—in particular, applied teachers’ identification and correction of students’ errors. She continues to research teacher effectiveness, effective practice methods, and best practices for error correction.  

Dr. Keech has a bachelor’s degree in piano performance from Acadia University, where she studied under Prof. John Hansen, and a master’s in piano performance from McGill University, under Profs. Marina Mdivani and Sara Laimon.  

While her university training is in classical music, she has broad experience performing piano music in other styles: jazz, blues, folk, congregational, show tunes, Latin-American, and pop. As an accompanist, Dr. Keech is especially recognized for her rehearsal and performance skills in choral settings. She has worked with the Annapolis Valley Honour Choir, Nova Scotia Youth Choir, Canadian Chamber Choir, and numerous internationally renowned choral conductors (e.g., Elise Bradley, Scott Leithead, Michael Zaugg). She has been on the accompanying staff at Acadia, collaborating with and coaching woodwind students. As a gig musician, she continues a busy schedule of playing and singing at weddings, conferences, church services, restaurants, and other special events.  

The guiding principle behind her research and teaching philosophy is the belief in the importance of the well-rounded musician, which includes being able to improvise and compose, in addition to the more traditional skills of learning to read and interpret Western music. Mistakes are also fascinating as they are inevitable and integral to the learning and creative processes. How do teachers, on the one hand, create an atmosphere where mistakes aren’t feared, where errors are embraced as learning opportunities, while on the other hand, maintain high standards of performance?  

In addition to teaching full-time at Acadia, Dr. Keech has also been operating a private home piano studio for over 25 years. She adjudicates at music festivals and conducts workshops on topics such as teaching students to improvise, how to practise, and the pedagogy of practice.
