## [A longitudinal study of the process of acquiring absolute pitch: A practical report of training with the ‘chord identification method’ - Ayako Sakakibara, 2014](https://journals.sagepub.com/doi/abs/10.1177/0305735612463948) > Twenty-four young children (aged 2 to 6 years) without AP (absolute pitch) were trained to acquire AP using Eguchi’s (1991) Chord Identification Method (CIM). All children were able to acquire AP (except two who ceased training). Would it be a good idea to teach Everette perfect pitch? I've heard it can sometimes be more of an liability than an asset. > It also makes it really difficult to play out-of-tune instruments. The piano in our local pub is a whole tone flat and it confuses the hell out of me... there's a mismatch between what my brain thinks I'm playing and the sound that's coming out. (https://news.ycombinator.com/item?id=35754398) The training process: [Perfect Pitch Program|ICHIONKAI MUSIC SCHOOL](https://ichionkai.co.jp/english4.html) > The main procedure of Eguchi Method Perfect Pitch Training System is listening to the chords and labeling them in "color" but not an actual pitch name. Each chord is applied different colors. Children do not perceive the chords as pitch names at first, but identify as a "color" image. ## VA Study on Long COVID Michael Mina comments here: https://twitter.com/michaelmina_lab/status/1651270977911750657?s=20 Massive selection bias makes the conclusions very misleading: > The authors look only at 2nd, 3rd, 4th infections that cause disease enough to cause someone to drive to the VA hospital and get a test The population funnel down from 1 to 3 infections spans multiple order of magnitude - and this drives massive bias! > 0 infections - >1M people 1st infection - 100,000’s of ppl 2nd - 10,000’s 3rd - 1000’s 4th - 100’s What they completely fail to discuss are the 100’s of thousands of ppl who get repeat infections and clear it w/out issue ## Meal Replacements in Weight Loss > Meal replacements assist with weight reduction because they provide nutrient density and energy reduction in a simplified food deliverable. In a world of ever expanding problematic convenience foods, MRs can help one navigate the food environment. (https://twitter.com/MichaelAlbertMD/status/1652430775600513024?s=20) [The Effect of Meal Replacement on Weight Loss According to Calorie-Restriction Type and Proportion of Energy Intake: A Systematic Review and Meta-Analysis of Randomized Controlled Trials - PubMed](https://pubmed.ncbi.nlm.nih.gov/34144920/): > **Conclusions:** The effect of MR-based LED on weight loss was superior to the effect of food-based LED, and receiving ≥60% of total daily energy intake from MR had the greatest effect on weight loss. ## Generate Podcast Summaries with GPT I've published some scripts to GitHub (https://github.com/beala/ai_tools) for summarizing podcasts using OpenAI's APIs.
