Participants will receive six weeks of individualized piano instruction and two weeks follow-up for a total of eight weeks.

During weeks two through seven, participants will receive a once a week, hour long, in-person individualized piano keyboard instruction as follows:

1. Warm-up

   1. Scales and Chords: Consisting of scales on seven major keys (C, D, E, F, G, A and B), chord progressions on I, IV, V, I. Two different keys will be learned every week.
   2. 5-finger exercises will be completed four times per week.

2. Piano Theory and Music

   1. Piano Theory: Playing through Alfred's Basic Adult All-in-One Course, Book 1, to be completed at the ability level of participant, with a least two new pages per lesson.
   2. Chosen Piece: Playing through an instrumental piece chosen by the participant.

Participants will be asked to practice homework from this lesson daily for 20 minutes per day, until their next weekly lesson.

An investigator-designed questionnaire will be administered to participants, assessing their opinions about the program. The questionnaire includes multiple sections assessing participant session attendance, the effectiveness of the program, and how enjoyable it was. Total percentage scores will be calculated for each section.

The Participants' attendance section scores range from "1" to "4" sessions. A higher number of sessions attended indicates greater perceived program feasibility.

Questions assessing program effectiveness asked participants about their daily and weekly piano routines. Responses range from "not very easily" to "very easily". A higher positive response percentage indicates greater perceived program feasibility.

Program enjoyment questions asked participants to rate their satisfaction. Responses range from "not enjoyable" to "very enjoyable".A higher positive response percentage indicates greater perceived program feasibility.

The National Institutes of Health Toolbox Cognition Battery (NIHTB-CB) will be administered to participants to measure change in cognition after individualized piano instruction. The NIHTB-CB consists of tests of multiple constructs, yielding individual test scores and the following summary scores: Total Cognition Composite, Fluid Composite (includes Dimensional Change Card Sort, Flanker Inhibitory Control and Attention, Picture Sequence Memory (Form A), List Sorting Working Memory, and Pattern Comparison tests), and Crystallized Composite (includes Picture Vocabulary and Oral Reading Recognition tests). Scores on the NIHTB-CB will be used to assess severity of chemotherapy-related cognitive injury (CRCI) in participants. Scores range from 59-140, higher scores mean better cognition.

The Generalized Anxiety Disorder Assessment (GAD-7) questionnaire will be administered to participants to measure the change in anxiety levels after individualized piano instruction. The GAD-7 consists of seven questions with each possible response scored on a four-point Likert scale ranging from "0" (not at all) to "4" (nearly every day). Higher total scores indicate greater severity of anxiety: 0-4 no to low-risk, 5-9 mild, 10-14 moderate, 15+ severe.
