🎹 Free beta: a piano app that listens to you play and tells you if you hit the right note (and I'm looking for a musician partner to write MusicXML scores)

Ever wanted to play your favorite song on the piano, then given up because the sheet music was impossible? I built Piano, a web app that walks you through each song step by step, and I'd love for you to try it. 🆓 It's free during the beta. Once it leaves beta it will cost $1, a simple one-time price with no confusing subscriptions. Anyone who joins now gets to try it for free and helps me polish it. What does it do? - 🎤 Listens to your piano through your microphone (or a USB MIDI keyboa

AI 分析

痛点:钢琴初学者因五线谱太难、缺乏即时纠错而放弃练琴,需要能听音判对错、按难度分级的陪练工具。

目标用户:自学钢琴的成年初学者、想弹流行/动漫/游戏曲目的休闲玩家,以及需要给学生布置曲目的钢琴老师。

变现:作者自定的 $1 一次性买断过低,难以覆盖获客成本。建议改为:热门曲目/难度包付费解锁($5-15 曲包)、教师端班级管理订阅($9-19/月)、MusicXML 交互式曲谱创作者分成市场。

MVP:2 周内用 Web Audio + 基频检测(如 pitchy/crepe)+ MIDI 输入做一个最小版本:3 首公有领域曲目、落键提示、单音对错判定、左右手分步解锁,用 Lemon Squeezy/Stripe 做 $5 曲包一次性付费,先验证付费转化再扩曲库。

竞品:Simply Piano、flowkey、Synthesia、Yousician、Skoove、Piano Marvel、MuseScore

摘要:作者在 r/SideProject 发布浏览器端钢琴陪练应用 Piano 的免费 Beta:通过麦克风或 MIDI 听辨音准、落键模式、三档难度与游戏化星级,支持 5 种语言、9 首曲目,正式版定价 1 美元买断。该需求真实但赛道极度拥挤(Simply Piano、flowkey、Synthesia 等),且 $1 买断价与『免费 Beta』表明尚未验证付费意愿,同时作者公开寻找 MusicXML 曲谱合作者,暴露了内容供给这一瓶颈。
