GTK - Guitar Player's Toolkitはどんなアプリ？
GTK - Guitar Player's Toolkitは、ギターの理論を指板上の位置と結びつけて学習するためのツールです。
数千種類のコードが含まれるライブラリから好きな音を選んだり、複数のスケールやコードを色分けされた画面で比較したりできます。三和音の構成や指の形を練習する機能があるため、理論を実際の演奏に落とし込む過程を視覚的に捉えられます。特定のキーで弾きたい場所の指の形を瞬時に導き出してくれる機能もあり、指を動かす範囲を限定して練習する際にも役立ちます。
自分の奏法に合うキーへコードを書き換えたり、メトロノームやチューナーで基礎を固めたいときにも重宝します。理論と実際の演奏の距離を縮めたい人や、指板上の全音の位置を正確に把握したい練習の場面に合っています。

GTK - Guitar Player's Toolkitの注目ポイント
指板上の全音の把握
特定の弦や音を選んで練習するメニューが用意されています。自分のギターで鳴る音とアプリ上の音を突き合わせながら、指板上のすべての音の位置を正確に覚えられます。
三和音の構成と形の習得
三和音の構成音や指の形を練習するツールが入っています。特定の弦のセットや転回形など条件を指定して練習するため、指板をより深く使いこなすための基礎を固められます。
数千種類のコードライブラリ
三千六百種類ものコードが登録された膨大なリストから選択できます。指の形は分かっているけれど名前が分からないといった場面でも、この機能で瞬時に確認できます。
複数のスケールの視覚的な比較
最大四つのスケールやコードを色分けされた指板上で同時に表示できます。共通する音を重ねて確認しながら、複雑な理論を視覚的に捉えて自分のものにしていけます。

Ver 1.7.6 2026-10-30
• Position Finder now follows your selected tuning — the mode and key lookup uses the lowest string of the current tuning instead of assuming standard E, and refreshes when you change tuning.
• Position Finder fret picker now reaches fret 24 (previously it stopped at 12).
• Position Finder shows the correct spelling for flat keys, e.g. {bold:Key of Eb} rather than D#.
• Refreshed app icon (with dark and tinted variants) and splash screen, with a larger splash image on iPad.

• Sometimes, the Tuner's accuracy wasn't properly reflected by the UX. Now shows a Locked / Listening… stability indicator so you can tell when a reading is settled and trustworthy, rather than mid-analysis.
• Tuner now holds your last reading on screen (dimmed) when the signal drops, instead of pre-emptively clearing it, and switches between notes more responsively when you test several in quick succession.

New Chords tab in Scales — Show notes from any chord name (type it in) and see all its notes across the whole fretboard, colour-coded per chord with pie-slice dots where two or more chords share a note and the root ringed. Draws on the same curated chord library as ChordMaster
Ver 1.7.3 2026-08-06
• New Scale Sharing tab in Scales - build a list of up to 4 scales and compare their notes on one fretboard, colour-coded per scale with pie-slice dots where two or more scales share a note.
• Scale Sharing bolds and colours each scale's {bold:root, 3rd, and 5th} in its notes list, and rings those same notes on the fretboard — a full ring on a solid dot, or just the relevant slice on a shared pie-slice dot.
• New Highlight Triad Notes toggle in settings under Scale Sharing lets you turn the fretboard ring highlight off for a plainer view.
• Triad Positions has moved from Position Finder to a new Triads tab in Scales, joining the Scale and Sharing tabs - it now shows chord tones across the full 24-fret neck (the fret From/To pickers are gone), with the fretboard scrolling horizontally and fixed string labels to match the other Scales tabs. Use the string-set checkboxes to focus the display. Your saved chord progressions carry over automatically.
• Position Finder is now a single, focused scale-position tool.
• Scales now shows a Diatonic Chords toggle for scales that have one (Major/Minor and their modes, Harmonic Minor/Major, Melodic Minor) — switch between the scale description and its diatonic chord sequence.
• Fixed Dorian, Phrygian, and Locrian descriptions in Scales, which previously showed a generic "Major scale" description instead of their own.
• Scale Sharing bolds and colours each scale's {bold:root, 3rd, and 5th} in its notes list, and rings those same notes on the fretboard — a full ring on a solid dot, or just the relevant slice on a shared pie-slice dot.

• Fixed chord search so name are detected automatically when entering accidentals (#/b) in unicode or not - applies to Chord Library and the Custom Chords search box.
• New Contact Us option in settings under Support - opens your Mail app with a pre-filled template so you can report a bug, request a feature, or send general feedback.

Ver 1.7.1 2026-07-15
• Position Finder now shows a Key / Mode toggle when the fretted position isn't the key's own root. This allows you switch between seeing note degrees and colours relative to the key you're playing in (e.g. G) or relative to the {bold:matched mode} (e.g. A Dorian). If you're playing in G, you should still see the option to focus on G scale notes, even if it is in a different mode's position.
• Corrected several inaccurate fret/mode pairings in Position Finder's help sheet Practical Examples - the displayed notes and mode names now match what the tool actually calculates.
• Fixed the Chord Diagrams setting in Settings - it previously had no effect; now renamed 'Show Finger Numbers' and correctly toggles finger-number labels on chord diagrams throughout the app.
• New Marker Colour option (Cyan, Indigo, Mint, or Pink) appears in Settings → Chord Diagrams when Show Finger Numbers is off, letting you choose the colour of the plain position dots.
• Chord Library now shows a notice when your selected tuning isn't standard. Its chord diagrams are curated for standard EADGBE tuning and won't match alternate tunings like Drop D or DADGAD
• Chord Master's Build and Explore tabs now show your current tuning in the navigation bar, confirming that fretboard positions and note names are calculated for the tuning selected in settings.

Ver 1.7.0 2026-07-09
Many planned updates delivered:
• Redesigned fretboards - strings and frets now render like a real instrument instead of a grid of cells.
• New Fretboard Skin option — choose Dark, Walnut, Rosewood, Ebony, or Maple.
• Scales fretboard now scrolls across the full 24-fret neck previously limited to 12 frets, with string labels staying fixed in place as you scroll.
• Fret position markers (the inlay dots at frets 3, 5, 7, 9, 12, 15, 17, 19, 21, and 24) now appear consistently on every fretboard.
• Fixed bidirectional arpeggiation Up then Down / Down then Up) in Chord Master and Chord Library — turnaround note now plays correctly on both passes, and notes no longer prematurely mute.
• Fixed slight fretboard string name misalignment.
