Gestalt Language Processing (GLP) is a type of language acquisition where individuals learn language in large chunks rather than individual words. Unlike analytic language processors (ALP) who break down language into its component parts, GLPs often begin by learning whole phrases rather than single words. Understanding GLP is crucial for music therapists who work with autistic clients, given that the predominant portion of this population are GLPs, as opposed to ALPs. GLPs are often seen as "intonation babies," emphasizing their natural attunement to the musical aspects of speech, such as rhythm, melody, and intonation. This innate sensitivity positions Registered Music Therapists (RMTs) perfectly to support their language development in a manner that aligns with their processing style.

Marge Blanc (2012) developed the Natural Language Acquisition (NLA) framework outlining the stages of GLP:
Stage 1: delayed echolalia. This is where children use whole gestalts or uses a string of intonational utterances that may or may not be intelligible but holds meaning. RMTs can use familiar songs to help GLPs internalise language chunks and associate them with meaning.
Stage 2: Mitigation, at this stage the individual will start to break down or mix and match parts of their gestalts. RMTs can support by introducing variations in familiar songs
Stage 3: Isolated Single Words. At this stage, the individual starts to understand that single words have meaning and begin to use self-generated language. RMTs can creative language generation by creating new lyrics.
Stage 4-6: Original Phrases, sentences and complete grammar. Individuals construct phrases, sentences and use increasing grammar. RMTs can support GLPs by using songwriting and story telling within a musical framework to extend on their utterances.

Using this NLA framework, music therapists can support GLPs by using music as a natural context for learning, promoting repetition and predictability, facilitating social interaction and encouraging creative self-expression. The presentation will include the differences between ALP and GLP, the important role of RMTs in facilitating language for GLPs, outline NLA stages for GLPs and describe how RMTs can support GLPs at each stage. This approach aligns with celebrating diversity in music therapy practice by fostering a therapeutic environment that is inclusive, supportive, and affirming. Embracing and understanding the unique needs of GLPs ensures that music therapy can continue to evolve as a dynamic and inclusive field, meeting diverse needs.
