Digital Musical Instruments in Special Educational Needs Schools: Requirements from the Music Teachers' Perspective and the Status Quo in Germany

Summary
This study presents the first comprehensive survey of digital musical instrument (DMI) use in special educational needs (SEN) schools, covering 745 schools across 12 of Germany's 16 federal states with a 41.5% response rate. The researchers surveyed 750 music teachers to understand the current status of DMI use, teachers' attitudes and motivations, and the perceived potential of DMIs for accessible music education. The authors define DMIs as computer-based systems consisting of an input device and sound generator, where the decoupling of input from output allows adaptation to individual movement abilities and cognitive needs. They categorize DMIs into eight types: digital versions of conventional instruments (keyboards), computer software (sequencers), music apps, haptic controllers (sample pads), touchless controllers (Soundbeam), breath controllers (Magic Flute), assistive music technologies (switches, talkers), and maker technologies (open-source self-built instruments). A key distinction is made between standard DMIs and accessible digital musical instruments (ADMIs)—those specifically designed for people with disabilities. The study tested two hypotheses: that teachers with rock/pop/jazz backgrounds use DMIs more frequently than classically trained teachers, and that better care ratios (fewer students per teacher) correlate with higher DMI use. Teachers ranked DMI capabilities by importance, with manageability, applicability in group settings, facilitation of discovery learning, robustness, and sound quality emerging as top priorities. Notably, teachers expressed strong preferences for simple instruments over complex ones, and for open-source technologies.
Key findings
DMIs are used in less than half (42%) of German SEN schools surveyed, and even in those schools, usage is infrequent. The most commonly used DMIs are digital keyboards and the GarageBand app—accessible DMIs (ADMIs) specifically designed for people with disabilities are virtually never used. Teachers from schools specializing in cognitive and physical development report slightly higher DMI usage (53%) than other SEN specializations (36%). A critical barrier is lack of knowledge: over 60% of teachers reported insufficient general, technical, and didactic knowledge about DMIs, and 84% identified inadequate training during their music education as a major obstacle. Teachers with classical music training use DMIs significantly less frequently than those with rock/pop/jazz backgrounds across all DMI categories, and they express more negative attitudes toward DMIs as substitutes for acoustic instruments. Exploratory factor analysis revealed four attitude dimensions: (1) DMIs facilitate self-efficacy experiences, (2) DMIs are easy to use, (3) DMIs are easy to adapt, and (4) DMIs require non-available knowledge. Teachers at schools for cognitive/physical development scored significantly higher on factors 1-3, suggesting more positive experiences with DMIs in those contexts. The care key (student-teacher ratio) significantly predicted usage of digital versions and assistive technologies—better ratios correlated with more frequent use, likely because these instruments require more individual support. Despite limited current use, 87% of teachers expressed interest in learning more about DMI possibilities, and 90% wanted a place to test different DMIs at their school.
Relevance
This research fills a critical gap in understanding why accessible music technologies remain underutilized despite their potential. The finding that knowledge barriers—not rejection of technology—drive non-adoption suggests that teacher training interventions could significantly increase DMI use. The 84% figure identifying lack of training during music education as problematic points to systemic issues in teacher preparation programs. For DMI developers, the study provides clear design priorities: manageability, group applicability, and robustness outrank individual-use features. The strong preference for simple instruments over complex ones (73% of schools) and for open-source solutions (71%) suggests that current commercial ADMIs may be over-engineered for educational contexts. The finding that most existing ADMIs are designed for solo use rather than group settings represents a significant market gap. The correlation between classical music training and negative DMI attitudes has implications for inclusive music education policy. If classically trained teachers view DMIs as inferior substitutes rather than instruments with unique value, students with disabilities may receive a diminished music education. The authors recommend that teacher training explicitly address DMIs' unique qualities rather than positioning them solely as accessibility accommodations. Practitioners should note that this study captures teacher perspectives only; student experiences remain unexplored. Germany's highly differentiated SEN school system may also limit generalizability to countries with more inclusive educational models.
