Abstract This paper is a single case study of a professional musician, PKC, with a selective impairment in reading, writing and understanding musical notation. After sustaining a left posterior temporal lobe lesion and a small right occipito-temporal lesion in an episode of haemorrhagic encephalitis, the patient showed a specific deficit in reading music. She retained the ability to read aloud letters, words, numbers and symbols, including the musical ones, but was quite unable to read aloud… 
A selective deficit in the production of exact musical intervals following right‐hemisphere damage
TLDR
This is the first detailed description of a dissociation between encoding and retrieval of melodic intervals in music, and the case of a 55‐year‐old high‐level amateur musician, IP, who had suffered a right‐hemisphere stroke.
Musical Alexia for Rhythm Notation: A Discrepancy Between Pitch and Rhythm
TLDR
A case of musical alexia and agraphia with Wernicke’s aphasia is presented, and the independence of rhythm reading and pitch reading is suggested.

The processing of music notation: some implications for piano sight-reading
Most piano pupils and many professional pianists find it difficult to sight-read music fluently. A major reason for this phenomenon is the complexity of the piano sight-reading process. Cognitive
To Play ‘B’ But Not to Say ‘B’: Selective Loss of Letter Names
TLDR
This paper is the first report of an aphasic patient (GT) who shows a selective impairment in naming musical notes and letters in the context of preserved instrumental reading of notes in terms of a selective deficit in the letter name system.
Hemispheric Asymmetries in Setticlavio Reading
TLDR
Results suggest that there is not a univocal hemispheric balance in musical setticlavio reading, reflecting several possible underlying reading mechanisms, and inversely proportional results between performance (both accuracy and reaction time) and distance from the reference clef (treble) suggest that settic Lavio reading is based on a spatial rather than verbal code.
Synaesthesia for Reading and Playing Musical Notes
TLDR
This study reports three cases of synaesthesia who experience colors in response to written musical notation, graphemes and heard music, and suggests that synaesthetic associations may migrate from one representational format to another.
Exploring the Association between Visual Perception Abilities and Reading of Musical Notation
TLDR
The results suggest that note-reading may be related to visual spatial processing abilities, and not to an individual's ability with object recognition.

Alexia without agraphia in a composer.
TLDR
His disorder fits the classic visual-verbal disconnection account of alexia without agraphia and the contemporary view that music involves a family of related but distinct skills probably involving many brain areas in both hemispheres, although different cortical areas make characteristic contributions to different musical behaviours.
Dissociation in Musical Reading: A Musician Affected by Alexia without Agraphia
Previous works have postulated a similarity between music reading and text reading. Therefore it is interesting to evaluate both of these functions in an alexic subject. The patient investigated is a

TLDR
Two aphasic right-handed professional musicians with left hemispheric lesions had disturbed musical function, especially musical alexia and agraphia, and in neither patient were those aspects of musical notation either closest to verbal language or most dependent upon temporal (sequential) processing maximally impaired.
Distributed neural network underlying musical sight-reading and keyboard performance.
TLDR
Using positron emission tomography and magnetic resonance imaging, the functional neuroanatomy of musical sight-reading and keyboard performance was studied in ten professional pianists to explain why brain damage in musicians may or may not affect both verbal and musical functions depending on the size and location of the damaged area.

TLDR
Data from a 77 year old right handed male blind, who presented with an infarction involving the territory of the left middle cerebral artery involving the temporal and the inferior parietal lobes, suggest the independence of linguistic and musical competences in an extremely talented musician.

TLDR
A well educated right-handed woman developed severe and stable alexia and agraphia following a circumscribed surgical lesion in the left premotor cortex, which point to the possible role of premotor cortices in the coactivation of precise sequences of motor and sensory activity patterns involved in reading and writing.
Music and Language in Degenerative Disease of the Brain
TLDR
The double dissociation between language and music functions supports the existence of independent cognitive systems, one consistent with conventional left lateralization models of language, temporal sequence, and analytic music processing and another with a right lateralization model of implicit music cognition.
